Top 5 Free TypeScript Courses to Learn Online - Best of Lot

If you are interested in learning TypeScript or Angular, one of the popular JavaScript framework for developing front-end, which uses TypeScript and looking for some resources e.g. books, tutorials and courses then you have come to the right place. In this article, I am going to share some of the best, free TypeScript online courses you can use to learn this powerful programming language. For those who don't know TypeScript, it's a new dynamically typed programming language from Microsoft which augments JavaScript's programming syntax by adding some new features which help in object-oriented application development, particularly introduction of Types.

As the name suggests, TypeScript is a combination of Types and JavaScript, which means now you have proper variables in your code e.g. a String or Integer variable and fewer type-safety related bugs to worry.

The good thing about TypeScript is that it compiles into native JavaScript code which can run on a browser, which means you now have a better syntax to write code and you can also take advantage of the ubiquitousness of JavaScript.



Why Learn TypeScript?

Most of the web developers are learning TypeScript because of Angular 2, one of the most powerful JavaScript framework and library. Google, which is behind Angular, chose TypeScript as the official language for Angular development, just like they have chosen Kotlin as the official language for Android.

In fact, I didn't know about TypeScript until I started learning Angular. But, there are more reasons to learn TypeScript and most important of them is more useful features which are required for modern JavaScript development.

The TypeScript contains several cool features e.g. Classes, Modules, Inheritance which takes application development to the next level. which will come in future JavaScript releases, which makes coding and development a to year than what it is now.

TypeScript is also used in WinJS which is the Windows library for JavaScript. You can use WinJS to make stuff for Windows Mobile and Windows 10 OS.

It also reduces bugs which are very common in JavaScript code and it's very difficult to debug and troubleshoot because of JavaScript's dynamic, un-typed format.

By using TypeScript, you can detect many such errors at compile time. The TypeScript compiler will warn you if you assign a string value to a numeric variable and vice-versa.

TypeScript is particularly useful for large JavaScript projects e.g. project with 10,000 lines of code. TypeScript projects are easier to maintain than JavaScript code.
