TypeScript Tutorials

TypeScript Tutorials – TypeScript adds types to JavaScript to speed up development by identifying problems before the JavaScript code is even performed. On top of JavaScript, TypeScript is an open-source programming language. It works in any browser, operating system, or environment that supports JavaScript.

TypeScript is a feature-rich version of Javascript for ES6 and higher (ES2019, ESNext, and so on), created and maintained by Microsoft under the Apache 2 license.

TypeScript code cannot be run directly in the browser; instead, it is compiled into Javascript code, which may be run directly in the browser. Any .js file that is legitimate can be renamed to .ts and compiled with other TypeScript files.

Why should you learn Typescript?

  • TypeScript is a more secure alternative to JavaScript.
  • All Javascript libraries are supported by TypeScript.
  • TypeScript is a simple, fast, and easy-to-learn programming language.
  • Because TypeScript is statically typed, the code it generates is more predictable and hence easier to debug.
  • TypeScript is portable, meaning it can run in any environment that supports Javascript. It does not require a virtual machine or a specialized runtime environment.
  • Classes, inheritance, interfaces, generics, and other OOP elements are supported by TypeScript.
  • Error checking is available in TypeScript at compile time.

This TypeScript tutorials will teach you how to:

  • Why TypeScript has so many advantages over plain JavaScript.
  • Learn what TypeScript is and how it works behind the scenes.
  • TypeScript’s powerful features, such as Types, Classes, Interfaces, Modules, and more, can be used.


  • JavaScript basics are required.
  • You understand how to install software on any operating system.
