TypeScript has rapidly grown in popularity over the last few years. Originally created by Microsoft in 2012, TypeScript adds optional static typing and other powerful features on top of regular JavaScript. While JavaScript remains an extremely popular language, TypeScript offers some clear benefits that are making it the preferred choice for many developers.

In this post, we’ll take a look at what TypeScript is, its key features, and why it has become so widely adopted.

What is TypeScript?

TypeScript is a superset of JavaScript that compiles down into regular JavaScript. This means it adds new syntax and features that aren’t supported natively in JS. The key difference is that TypeScript is statically-typed while JavaScript is dynamically-typed. This means TypeScript allows you to specify types for variables, function parameters, return values, and more.

Key Features

Here are some of the major features TypeScript offers:

  • Static typing for safer code and easier debugging
  • Object-oriented features like classes, interfaces and generics
  • Richer intellisense and autocompletion in editors
  • Easier refactoring of large codebases
  • Non-JavaScript features like tuples and enums
  • Modern ES6+ features compiled down for older browsers

Why TypeScript Has Taken Off

So why has TypeScript taken off so quickly? There are a few key reasons:

First, it has strong backing from Microsoft and is deeply integrated into Visual Studio, VS Code, and other Microsoft products. The tooling support is excellent.

Second, Angular — one of the most popular web frameworks — is written in TypeScript. This provides a killer app that encourages adoption.

Finally, static typing helps reduce bugs and makes large JavaScript codebases much more manageable. The safety and readability benefits appeal strongly to teams and enterprises.


In summary, TypeScript has rapidly emerged as an essential tool for modern JavaScript development. Its optional typing, advanced features, and tooling support make it a clear winner for building robust web apps. While plain JavaScript is here to stay, TypeScript offers key benefits that appeal to individuals, teams, and enterprises alike. Learning TypeScript can give your programming skills and career a big boost.
