Reasons why every web developer should learn Node.JS

Web developers are in demand across the world — but it’s the Node.JS developers that get the most attention. So much so that, in the list of most in-demand jobs, the number of jobs related to Node.JS has increased by around 2500% over the last few years.

According to the official Node.JS source, the number of downloads for Node.JS increased by 49% in 2018 alone. There’s no denying that the use of Node.JS in production sites has dramatically increased since its release back in 2010.

With big players like LinkedIn, PayPal, and other tech companies jumping the gun to try out Node.JS and build their platform using it, the language has seen a tremendous increase in its used in web development. It is certainly the more popular language when you compare it with other web-dev technologies.

It can be said without a doubt that for those starting out, Node.JS seems to be the most sensible way. Let’s see some more reasons as to why every web developer (and not only just freshers) should learn Node.JS:

Compared to other web development technologies, Node.js is more popular. For people looking to start their career in web development, starting with Node.js makes more sense than any other. Below are some facts about Node.js that would compel you to learn it.

1. Unstoppable demand

Node.JS, as a language, has seen unprecedented growth in its demand. In fact, it has even overtaken Java = the most popular programming language so far.

The graph above clearly indicates that Java is slowly losing its popularity, while Node.JS is only gaining it. As a developer, you are entitled to say that the comparison between Java and Node.JS is not quite right.

However, if you look at the Stack Overflow Developers Survey that was taken in 2018, you’ll find that JavaScript is the most famous programming language, followed closely by Java. But if you compare the growth of Node.JS and Java, you’ll realize that Node.JS is a clear winner in this aspect.

2. Increase in the number of jobs in Node.js

This point literally follows the first one. If a particular technology is popular, both among developers and companies that require those developers, the number of jobs related to that technology is bound to increase by leaps and bounds.

Node.JS requires less development time, fewer number of servers, and offers an unparalleled scalability — all of which make it an ideal choice for companies looking for a solid backend to their website. Straight from the horse’s mouth, companies like LinkedIn are using it because of the significantly reduced their development time, while Netflix says that it improved their application’s loading time by approximately 70%. Other prominent names in the tech industry that use Node.js includes Medium, The New York Times, PayPal and so on. Gradually, start-ups are catching up on this trend too, incorporating Node.js as part of their technology stack.

3. JavaScript is an extensive language

The best part about Node.JS is the JS. It uses JavaScript which is the most popular and the simplest way to develop applications for the browser. You can ofcourse do it with other programming languages, but none of the offer the ease that JS does.

Generally, if you’re to develop browser applications and server side applications, JS is an additional language you need alongside PHP, Ruby, or Python. Node.JS helps you remove the need for an additional language as it allows you to use JavaScript for both browser-side as well as server-side applications.

Compared to other languages like Python and Ruby, JavaScript proves to have better performance. Add to that the lesser room for human error, as Node.JS helps programmers avoid mental switching between a browser-side language and a server-side language.

4. Get the full stack under your control

Getting control of the full stack requires you to be comfortable with both front-end as well as back-end. Previously, in order to do so, you had to know a server-side language in addition to knowing JS. With Node.JS, however, JS can be used as the base language for all front-end as well as back-end work. Node.JS can be used with JS front-end libraries like Express.js, Angular, and more, you can start working as a Full Stack Developer.

5. Good salary packages

With so many large players recruiting for the Node.JS developer position, the pay scale is also considerably better than that of other technologies. For freshers just starting out in Node.JS development, the salary can be anywhere between 6–10LPA. This entirely depends on your skill set and experience with the language.

Overall, as the demand for Node.JS keeps on growing, there’ll always be a need for a skilled Node.JS developer in some company or the other. It’s the perfect language if you’re looking to accelerate your growth in the industry.

Keeping all this in mind, let’s present to you the Node.JS course offered here at Coding Ninjas. The curriculum is designed keeping everyone in mind and the exercises provided along the way ensure that you have a solid path to walk on. Come on in!

Brain food: Affordable healthy snacks to get your brain running

What is the one thing that programmers around the world can agree on, regardless of the variety of differences they have? The job requires constant and rigorous brain activity — to churn out the best logical solutions. To put the pro in programming, a programmer must have their brain at its best functioning, at all times; and for that to happen, the brain needs special food (like every program needs a special code).

Here’s a list of most efficient, but budget-friendly fuels for your brain, to keep it and your pocket at their healthiest.


Let’s start with the base that will support everything — Water. The cheapest and most essential. Our brain is 73% water, which is enough to convince you how important hydration is for it. Give it what it’s made of! There are studies which indicate a decrement in cognitive performances at dehydration levels of as low as 1%; whereas lower dehydration levels at 2% show adverse effects on visual-motor tracking, short term memory, and a decline in attention. Make sure that your water intake is at least 2.7L — 3.7L (11–15 cups) every day to adequately meet your daily hydration needs.


Foods rich in carbohydrates with lower Glycemic index or GI value (below 70) are the best for your central processing unit — the brain. Prefer whole wheat or whole grain food over white flour food. These are high in carbohydrates and have a low GI value. Here is an abbreviated data of the Glycemic Index for such cheaper and healthier food:

  • Wheat roti — 62 ± 3
  • Chapati — 52 ± 4
  • Barley — 28 ± 2
  • Sweet Corn — 52 ± 5
  • Spaghetti — 48 ± 5

Breakfast Cereal;

  • Porridge — 55 ± 2
  • Muesli — 57 ± 2


  • Apple — 36 ± 2
  • Orange — 43 ± 3
  • Banana — 51 ± 3
  • Pineapple — 59 ± 8
  • Mango — 51 ± 5
  • Dates — 42 ± 4


  • Boiled Carrots — 39 ± 4
  • Boiled Sweet Potato — 63 ± 3
  • Vegetable Soup — 48 ± 5

Dairy Products;

  • Full Fat Milk — 39 ± 3
  • Skimmed milk — 37 ± 4
  • Ice Cream — 51 ± 3
  • Yogurt — 41 ± 2


  • Chickpeas — 28 ± 9
  • Kidney Beans — 24 ± 4
  • Lentils — 32 ± 5
  • Soya Bean — 16 ± 1


Vitamins and minerals are extremely crucial as they work as fertilizer-and-manure for your brain. We fulfill most of our VnM quota through our food, but some essential vitamins such as D3 is only produced and processed when exposed to direct sunlight, so get up, and go out for that stroll. Some other essential vitamins for the brain are B1 (Thiamin) and B9 (Folate) which can be gained by the following;

  • Salmon
  • Barley
  • Papaya
  • Oatmeal
  • Green Peas
  • Soft Tofu (Paneer)
  • Soyabean
  • Lentils
  • Broccoli
  • Mangoes
  • Sweet Corn, and
  • Oranges

Analogously, minerals like Magnesium and Zinc work for our brain in the same way as spinach does for Popeye. You can get all you Magnesium and Zinc from:

  • Whole Wheat
  • Dark Chocolate
  • Spinach
  • Almonds, Cashews, and Peanuts
  • Eggs
  • Chickpeas
  • Lamb

Essential Fats

Contrary to the common belief, the complete elimination of fatty foods from your diet will do more harm than good. While “Trans Fat” is the bad guy, your brain still needs “Essential Fatty Acid” as it is technically a big chunk of fat inside our skull. As a matter of fact, an omega-3 fatty acid, DHA, is a major structural part of our brain tissue. Including food rich in Omega-6 (Linoleic Acid) and Omega-3 (Linolenic Acid) in your diet will prove to be the best plan to guard your brain against corrosion. You can get these from:

  • Chia Seeds
  • Walnut
  • Soyabean
  • Flax Seeds
  • Pistachios


Now that you know the entire code to run your brain without any errors, make sure to keep eating light healthy snacks in proper intervals throughout the day, and exercise regularly.

Incorporate all this in your diet slowly, and develop a habit of healthy eating without going too harsh on yourself (you’re always allowed a few cheat days here and there).

And to get an idea as to how these food items are helping you grow your brain and perform better at your tasks, why not jump straight to Coding Ninjas where we offer you a variety of courses for you to select from? You have the best nutrients coupled with the best mentors with you — there’s no stopping you from rising to the top!

Here’s why you should consider ruby on rails for your web development projects!


With the rapid growth of the ‘online’ scenario, websites and web apps are the rage now. And why not?

When you can access anything you need with just a click of a button, be it information or be it that super cool product that’s making headlines — you can get anything and everything online!

This is why smart business owners are readily shifting to the online domain to extend their reach to the vast pool of netizens who’re always on the lookout for awesome websites and applications. Now, coming to the important question — do you know which programming language takes the crown for web dev?

It’s Ruby on Rails of course!

What is Ruby on Rails (RoR)?

Ruby is an Object Oriented programming language and a cross-platform web development application built on top of Ruby. One of the best features of RoR is that it is open-source. Also, RoR leverages the Model-View-Controller (MVC) architecture and comes with a rich array of useful libraries. Such features allow programmers and developers to build highly database driven websites.

Why choose Ruby on Rails for web development?

Here are reasons why you should choose Ruby on Rails for your next web dev project!

1. Super easy to learn!

This is perhaps the most commendable features of RoR that makes it extremely beginner-friendly language. With a simple syntax and code generation style, RoR is very easy to learn and understand. It uses simple English and a domain-specific language approach. So, things are never complicated with RoR.

2. It is open-source.

As we mentioned before, RoR is an open-source framework and hence, it is absolutely free of cost. This makes it an excellent choice for startups and emerging businesses that have limited financial resources.

3. Fantastic libraries!

Another feather in the cap of RoR is its rich and extensive library support. These libraries are so useful that they can speed up the process of web development to a great extent. In RoR, libraries are known as gems which can be easily combined with basic functions of the language. Then there are modules that can be used for arranging classes, constants, and so on.

4. It is highly scalable.

It is a known fact that Ruby is a highly scalable and reliable language that allows you to perform a number of tasks seamlessly. For instance, as Ruby supports the caching function, you can check out the fragment caching within an app’s code. Then again you can use its multi-server automation tool that not only helps to automate variants of a new application but also deploy it to a location. The advantage of the Rails framework on top of Ruby is that it allows programmers/developers to leverage the Chef platform — a cloud infrastructure that helps manage the infrastructure dependencies for the development of folder structure.

5. It is all about clean coding!

RoR supports a simple and neat coding syntax. RoR principles like REST (Representational State Transfer), COC (Convention Over Configuration), CRUD (Create, Read, Update, Delete), and KISAP (Keep It Simple As Possible) allow for faster and cleaner code generation, devoid of any redundancy.

Also, RoR supports agile software development wherein tasks are divided into smaller chunks for the ease of execution.

If these aren’t enough, you should know that RoR is the secret sauce behind some of the most successful websites including Shopify, Twitch, GitHub, Airbnb, Hulu, Zendesk, SoundCloud, Yellow Pages, to name a few. To conclude, RoR is a highly efficient and powerful web development tool that has been embraced by millions of developers across the globe.

You too could master Ruby on Rails by enroling in our inclusive course on Web Development with Ruby on Rails! The course will help you get started from ground-zero. By helping you understand coding logic, and inculcating the thinking of a developer, this course will help you create beautiful web applications with ease.

Also, if you’re just starting out with web development and are looking for the best language for you, let’s also tell you a bit about Node.js. Head over to our blogs to read more about Node and the benefits it offers and make an informed choice!

Emergence of chatbots

Every active Netizen has interacted with a Chatbot at some point in their life. You must have too! Ever noticed those tiny pop-up windows greeting you with a “Hello, how may I help you today?

These are chatbots that have been designed to communicate with you. You must have heard about Siri. What is Siri? She is a super intelligent chatbot (with loads of mindblowing and quirky answers up her sleeve!)

Are you wondering how did these smart and sophisticated chatbots come to be? We’ll break it down for you!

Chatbots — What are they?

Chatbots are essentially a software designed to communicate with humans in their natural language. And believe it or not, chatbots have been around us longer than you can imagine.

The first chatbot — ELIZA — was developed way back in 1966 by Joseph Weizenbaum. He had programmed ELIZA in a way that it could imitate the language and behaviour of a psychotherapist. The next development in the field came in 1972 with PARRY, another chatbot. These early chatbots could interact only through textual commands and responses. The first voice operated chatbot came to the scene in 1988 — Rollo Carpenter’s Jabberwacky project.

As time passed, more advanced chatbots came into being such as A.L.I.C.E and SmarterChild. Today, we have some of the most exceptional chatbots amidst us — Siri, Alexa, Watson, Cortana, and so much more!

The chatbot drive

The latest stats show that chatbots are becoming popular by the minute. According to a Forrester report, nearly 57% of firms across the globe have either already invested in chatbots or are planning to in the near future.

Companies are rapidly incorporating chatbots within their system and rightly so. Chatbots have displayed an immense potential to enhance the entire customer service scenario by leaps and bounds. While Scripted Chatbots work according to predetermined rules, AI-powered Chatbots are way smarter.

The AI-powered chatbots of today use natural language processing to understand human commands (text and voice) and learn from previous experiences. So, a chatbot first soaks in the information you provide to it and then analyzes it with the help of complex AI algorithms, and finally responds to your query with a written or spoken result. As these chatbots have the capability to ‘learn’ from behaviour and experiences, they can respond to a wide range of queries and new commands.

This ability of chatbots has made them extremely appealing to companies who have an online presence and wish to create a more enhanced customer experience.

In a research conducted by Forrester, it was found that messaging happens to be the №1 customer service channel preferred by consumers in the US, India, South Korea, and Singapore. Unlike humans, chatbots can work 24×7 and hence, they can provide round the clock assistance to customers. Chatbots can take over the mundane tasks of human employees and can perform them much better. Also, chatbots can handle several queries at once, so no more waiting in queue for a response to your query.

Using a chatbot can help companies save a ton of money that would otherwise go into paying human employees for performing the same task. According to Juniper Research, chatbots helped businesses save nearly $20 million.

But that’s not all that chatbots can do.

In May 2016, Google unveiled Allo, a smart messaging app. Allo comes with Google Assistant and can help users perform a wide range of tasks, from finding information on the Internet to making dinner reservations! Then again, many companies have started using Facebook’s Messenger bot service that allows them to create a bot in Facebook Messenger that interacts with consumers without them having to ever leave the platform to access another app or another website.

Chatbots — The future

Satya Nadella, the CEO of Microsoft is quite optimistic about the future of chatbots. At the Build 2016 Conference, he stated:

“As an industry, we are on the cusp of a new frontier that pairs the power of natural human language with advanced machine intelligence.”

Judging by the rapid progress that chatbots are making in the present day, it can be safely assumed that in the near future we will get to see even more sophisticated bots (maybe even more so than Siri and Alexa!). For instance, if chatbots are collated with video service apps like YouTube, we may be able to create a new dimension of e-learning wherein the bots would function as learned instructors. With the right mix of technology, there may emerge many such groundbreaking opportunities.

Python for Machine Learning


Machine Learning — a term you’ve probably heard of unless you were living under a rock since the past 2–3 years. But what exactly is it? To put it in simple terms, whenever you shop from amazon for a mobile phone, it suggests you a case or a screen protector for that mobile phone. Or when you buy a t-shirt online it also suggests you jeans and shoes. It predicts your future by analysing your browsing history and time spent on a single product before buying it. There are 3 types of learning algorithms which make it so powerful. Supervised, Unsupervised, and Semi-Supervised Learning. We won’t dive into the specifics of it but basically supervised learning is the data which you give to differentiate between two objects while unsupervised learning is data that hasn’t been labelled by the user. Semi-Supervised learning, on the other hand, is the data which is half-fed for example a large amount with a small amount of labelled data.

Machine Learning has become extremely important in almost every spheres. So much so that it can predict, with certain assurity, when are you likely to have a heart attack based on your electrocardiogram tests. Fascinating, right? Tech CEOs have praised Machine Learning and almost bet that it’s going to be a big deal in the next 10–20 years. Sundar Pichai, the chief executive officer of Alphabet’s Google said he sees a “huge opportunity” in ML. While Jeff Bezos, the richest man on the planet and also CEO of Amazon said, “It’s really early but I think we’re on the edge of a golden era. It’s going to be so exciting to see what happens.”

You can see Machine Learning at work in almost all parts of your life, for example: Google Assistant- the voice recognition assistant uses Machine Learning to differentiate between voices and accents. Amazon Alexa, Amazon dot com use Machine Learning to improve your experience throughout the amazon ecosystem. If you have Face ID on your iPhone X or later, it uses Machine Learning to calculate the number of dots on your face and unlock the phone- all under the span of 10 milliseconds. Cool, huh? It uses what is called Deep Neural Networks to create a mathematical model of your face.It is expected to solve problems that were merely a science fiction back then.

Using Python for Machine Learning

Python is mainly a scripting language that is very easy to learn compared to other programming languages like C++ and JavaScript. It doesn’t require a lot of programming expertise, and if you’re able to think logically, half your work is done — because Python doesn’t rely a lot on syntax.

Python has a larger user base compared to many other programming languages which means more people would be able to understand and participate in your work which makes it easier to work on new technologies from scratch. Developers can find tutorials and tips in the development process. Unlike other languages, Python maintains clean and concise code throughout the project which helps in writing complex algorithms and maintaining them. Python user community has developed many modules to help programmers implement machine learning such as SciKit and Theano. These modules are well-documented to help you step-by-step on your first project. The development is fast and stable which speeds up the process by a lot when fixing bugs.

Advantages of using Python

  • Ease of Use- Python is very easy to use and developers can quickly start adapting to the language.
  • Speed- There is less work required in a code as compared to other languages which saves time.
  • Reliability- The Modules are well documented which makes the experience a bit easier.
  • User base- Thanks to the huge user base Python has to offer, more people can get involved in your project and help iron out the bugs.
  • Huge Library- Already built libraries such as SciKit and Theano makes for a good start for a beginner.
  • Integration through all operating systems- It can run on all modern operating systems through the same code. So for example you could build a project in MacOS, Test it in Linux and upload it through Windows.


In the end, it’s all about personal preference, some people prefer other programming languages for their projects, some people prefer Python. C++/Java can also be used for Machine Learning but it’s the simplicity of Python that makes it the most popular language for Machine Learning.The integration, huge number of libraries and an active community are a huge plus if you’re a beginner trying to get into Machine Learning, Python is a great programming language to kick start and explore the vast capabilities Machine Learning has to offer. It is an extremely accessible language to learn and begin scripting in, important for people coming from non-software backgrounds.

Now that you’re well versed with the benefits that Python offers, it’s time you get yourself started with it. Why not come by and check out the Python courses offered by Coding Ninjas?  We also offer courses on Machine Learning to ensure you’re on the correct path right from the start.

Everything you need to know about website personalization


Everyone likes things curated ‘exclusively’ to your website’s users liking is what website personalization is. It denotes the process of creating, curating, and delivering tailor-made experiences for your customers/visitors. So, instead of creating an all-encompassing experience for your entire customer base, you’ll be creating a unique experience for each of your user segment, based on their unique tastes and preferences.

The benefit?

Your customers will feel like you care for them and their individual needs. Not only will their satisfaction quotient increase but you will also gain their loyalty. Also, it will boost your customer engagement to a great extent.

But what are the different types of web personalization?

There are primarily three different kinds of web personalization:

Navigational personalization –

Navigational personalization is a method that leverages a consumer’s browsing behaviour and purchase history. So, by understanding these two patterns, you can easily customize the online experience for your consumers, more precisely, how they navigate around in your website. For instance, you host an online shopping website, and a certain potential customer is eying a particular dress but due to some reason, he/she leaves the platform without buying it. Now that you know that the customer likes that dress, maybe you can minimize its price or provide some discount offer on the dress and prioritize the dress in the recommendation engine in a way that it appears on the forefront. So, the next time the customer visits your site, the chances of him/her buying that dress will increase.

Predictive recommendation –

While shopping on an online portal, you must have come across lines such as “If you like this you might also like this…” or “Customers who brought this…”. Such tags are extremely common on online platforms nowadays. While browsing such lines persuade you to check out similar items on a particular platform so you know you have numerous choices. This is your personalized recommendation engine that predicts your preference pattern and curates specific buying suggestions for you.

Contextual messaging –

Contextual messaging is a method where marketers customize messages for their customers/potential customers based on an array of factors including location, preference pattern, buying behaviour, opening behaviour, to name a few. This allows them to create such messages and emails that capture their consumers’ interests and address their pain points with much higher relevance.

Now that you know the tidbits of web personalization, let’s look at the ways you can create an awesome web personalization strategy!

1. Extract behavioural data and put it to good use!

It is a really frustrating experience for consumers when they find nothing suiting their interests and needs on an online platform. However, you can prevent this from happening by tracking the consumer browsing behaviour, their search history, their preference patterns, and so on. These little cues will not only help you understand your customer segments but they will also help you create the perfect ads and marketing campaigns to best suit their needs. Amazon’s recommendation engine is an excellent example of leveraging behavioural data.

2. Location-based personalization is the way to go.

Another very important way of curating a personalized experience for your niche audience/consumers is through location-based personalization. This is because the needs of consumers vary from location to location. For instance, a consumer residing in a cold country will not be looking for a pair of shorts but rather a warm jacket. Similarly, a resident of sunny California will not be looking for a jacket but rather a pair of cool shorts. You get the drift right? So, your ad campaigns and marketing techniques must be well thought of according to the location of your consumers.

3. Personalized recommendation lists are a hit!

You know what’d attract your potential consumers/audience the most? If you created a website that spoke to them at an individual level and not on a general line. To create personalized recommendation lists, it is first essential to identify your buyer personas. Once you do that, you can develop highly curated and customized online experience for your customers, so much so that it might even transform visiting customers into buying customers!

By implementing these tactics, you can offer a great online experience to your consumers. After all, a satisfied customer is a happy customer. If you go to various lengths to show your customers that you care for them, they will always be back for more. Smart move to grow your business, right?
