TypeScript Tutorials [Beginners + Advanced]

I highly recommend checking out Typescript tutorials, as Typescript has become popular in the last few years, and many companies are asking for knowledge in Typescript to use in project development.

If you know a little JavaScript, it will become easier for you to learn Typescript. But even if you do not know JavaScript, you can start with our Typescript tutorials for beginners and then continue with the advanced typescript tutorials.

Let us start.

Introduction to TypeScript

TypeScript is a powerful, statically typed superset of JavaScript that compiles to plain JavaScript code. Originally developed by Microsoft, TypeScript brings robust typing, powerful features like interfaces and generics, and advanced development tools to the world of JavaScript. This article aims to provide a comprehensive guide on what TypeScript is, its benefits, and why you should consider learning it, particularly if you’re in the United States, where demand for TypeScript skills is rising.

Features of TypeScript

Strong Typing

TypeScript allows you to define types for your variables and function parameters. This makes it easier to catch errors during compile-time rather than runtime.

Class-based Object-Oriented Programming

TypeScript brings traditional OOP concepts like classes, interfaces, and inheritance to JavaScript, which is originally prototype-based.

Easy Maintenance

The strongly typed nature of TypeScript makes it easier to maintain and refactor codebases, leading to lower development costs in the long run.

Compatibility with JavaScript

Since TypeScript is a superset of JavaScript, any valid JavaScript code is also valid TypeScript code. This ensures easy integration with existing JavaScript libraries and frameworks.

Why Should You Learn TypeScript?

Below is a table listing some key reasons why learning TypeScript can be beneficial for you.
