Top 6 Free Courses to Learn TypeScript in 2024 - Best of Lot

If you are interested in learning TypeScript or Angular, one of the popular JavaScript frameworks for developing front-end, which uses TypeScript, and looking for some resources like 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 that augments JavaScript's programming syntax by adding some new features which help in object-oriented application development, particularly the 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 like a String or Integer variable and fewer type-safety-related bugs to worry about.

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. You can also take advantage of the ubiquitousness of JavaScript.

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 like a project with 10,000 lines of code. TypeScript projects are easier to maintain than JavaScript code.  Btw, If you don't mind paying some money for the online course, then Understanding TypeScript by Maximillian of Academind is probably the best resource you can get to learn TypeScript online at this moment.

Why Learn TypeScript Programming Language in 2024?

Most web developers are learning TypeScript because of Angular 2, one of the most powerful JavaScript frameworks and libraries. 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 the most important of them are more useful features that are required for modern JavaScript development.

The TypeScript contains several cool features like Classes, Modules, Inheritance, which take 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 challenging to debug and troubleshoot because of JavaScript's dynamic, un-typed format.
