Why Learn Javascript in 2018 ?

 

What is Javascript?

 

JavaScript (JS) is one the most popular programming languages in the world right now, you can go and take a look at the Github Programming Ranking. Once supposed to a web front-end language now JavaScript run also on Backend servers, database servers, Mobile Front-ends and Hardware interfaces. JavaScript also making its marking world of hardware. Projects like Arduino and NodeBots have been showing that Javascript can become the primary language of embedded systems anytime now.

First of all, JavaScript has no relation to ‘Java’ programming language. JS was intended to have some interactive feature designed for a browser like small popups and button interactivity. It was considered as non-important part of the web and hence initial browsers used to block JS or had an option to block JS. Nowadays it would be a rare thing to block Javascript.

Ajax

 

JavaScript got into prominence due to AJAX calls and later due to development of NodeJS environment. Let’s talk about both of these in a little detail.

AJAX stands for Asynchronous JavaScript and XML which was considered to be a new technique to update HTML web pages in your browser without reloading pages. This was not possible with old-style web pages where every interaction used to load a new page. Imagine how you feel – clicking a Like button in Facebook and whole news feed reloads. Crazy it may sound but that was real web back in the 2000s – later JS provided the ability to load data only in part of the page.

How did the NodeJS revolution happen?

 

After AJAX and jQuery which was a shortcut toolset for writing JS codes next big revolution was NodeJS server development. NodeJS made JS more usable in any environment whether it is a Web Server or desktop application. It was based on chrome V8 engine which is an efficient compiler of the JS language. Suddenly a new world of JS as a programming language emerged out. It was considered as a front-end language but now it became a full-stack language with the huge number of web framework coming in next few years like Express, AngularReactVueJS and many more.

 

Modern JS Frameworks

 

In the Modern day of web development, JavaScript still controls front-end web development with frameworks like AngularJS and ReactJS covering the majority of front-end development work in big enterprise front-ends. Vue as also emerged as a top choice of many developers and it is a very highly growing framework in open source community (check out Github). With the advent of the Cross-Platform application based on web engines we now also have Mobile Apps made in these JS frameworks. Few of the popular frameworks are – Angular, Ionic, React and React Native.

What future holds for JS?

 

However to accommodate all these changes JS has changed a lot. It was weakly typed language and had no data types explicitly defined. Now JS has taken the recommendation of ES6 and ES7 which are the new version of JS these versions have some more features like class notations and short forms for callbacks. Some languages like TypeScript is a syntactical superset of JavaScript, with optional static typing and class-based object-oriented programming to the language.

Looking at the companies involved in JS development you will see that all major player in the modern world is working on some aspect of JS. Google is maintaining the AngularJS framework along with many others, Facebook is leading the React JS camp, IBM is taking care of StrongLoop which acquired express which was the defacto NodeJS framework. Microsoft is working on Typescript which is considered as a new standard of write highly scalable JS programs.

As you may have seen from this discussion that JavaScript is everywhere, it is in front-end of Web and Mobile, It is in backend servers, real-time databases, application interfaces and Internet of Things devices. The ubiquitous nature of JavaScript makes it number one choice for a modern age developer to know it.

 

Youstart Labs is providing many JavaScript Framework training to students and corporates from more than 3 years now and we have seen how the industry is looking for these candidates. It is the best time to learn a language which can be multipurpose and used everywhere and on every device.
