Why it's the right time to learn TypeScript.

In Today's world, If you are an web developer and you don't know JavaScript then you will feel left behind. It's never been a good time to be a JavaScript developer than now. With the rise of Node.js  JavaScript is everywhere now. But as you know when Size and Complexity of your JavaScript is Increased it's very difficult to maintain and mange. That's where TypeScript comes into picture. It is a life saver some times. So in this blog post we will see Why It's the right time to learn TypeScript.

What is TypeScript?


TypeScript is a free and open sourced programming language developed and Maintained by Microsoft. It works as a super set of JavaScript. As we all know that JavaScript is very liberal language by nature. So that we tend to make more mistakes and we does not know all the errors at run time. TypeScript is a strict super set of JavaScript so that you can get most of errors at compile time only.  As per official website of TypeScript it's a language that lets you write JavaScript in the way you really want to. TypeScript offers all the features that you need for Object oriented programming. You can find more information about TypeScript on it's official web site on below link.

ECMAScript and TypeScript:


ECMAScript is the specification standard of the JavaScript. So right not standard stable version if ECMAScript 5 and some of the browsers support ECMAScript 6. ECMAScript 6 features are being adopted by latest browsers.While TypeScript follows most of syntax of ECMAScript 6 so that you don't have a feel of the learning new language. As per official road map of Typescript 1.6 comes with ES6 Generator so you can convert your script code into ECMAScript6. Your can find more about that on following blog post.

TypeScript is everywhere:


As we know TypeScript is a fully Object Oriented language, It's provide great productivity boosts than JavaScript and it's super set of JavaScript so it will be compiled into JavaScript itself. So because of this lots of great framework started using TypeScript like following.
  1. Angular JS
  2. Iconic Framework for creating frond end mobile App
  3. Native Script from Telerik is also completely written TypeScript itself.
Take a example of AngularJs, It is one of the most popular JavaScript Framework on earth. With Angular.js 2.0 it will be fully written with TypeScript.

Tooling:


Most of Web Development editor whether it's paid or free are having TypeScript tooling.  Most popular editors like Visual Studio, Visual Studio Code, WebStorm, Atom, Sublime text and Eclipse are having great tooling for TypeScript.

Why to use TypeScript:


Followings are reason why we should use TypeScript instead of JavaScript.
  1. Fully Object Oriented support with classes and interfaces. So It's a great productivity boost for any developer and easily maintainable and understandable.
  2. It's provide most of the errors compile time while JavaScript is more liberal than this. So less run time error means less bugs for your application.
  3. Refactoring is very easy in TypeScript compare to JavaScript.
So it's never been late. It is the right time to learn TypeScript. Hope you like it. Stay tuned for more!.
