When it comes to web development, you may have seen multiple programming languages used on the same website. Well, all the languages being used in web development serve different purposes. But do you know the difference between the two major programming languages: TypeScript and JavaScript?

Well, simply put, TypeScript is JavaScript with types, but JavaScript is not TypeScript. It might be a puzzle for you. As a developer, you might be hearing more and more about TypeScript or wonder what the difference between it and JavaScript is. While both are programming languages, their features, purpose, and usage can vary drastically, which means that you should know what to look out for before using either one in your next project. Here’s everything you need to know about TypeScript and how it’s different from JavaScript so that you can use them effectively in your next project.

What is TypeScript?

TypeScript is a coding language that combines the simplicity and readability of JavaScript with static typing and compiles checks of a statistically typed language. It was created by Microsoft and is a superset of JavaScript with additional features such as optional inferred type declarations, classes, and modules. Programmers use TypeScript to write programs that can run on both the browser and server platforms. The type system of TypeScript allows you to write clear, concise code by providing strong typing for variables, functions, and even other types.

Features of TypeScript

TypeScript has several features that make it easy to use:

  • It is a superset of the JavaScript language that you can use existing JavaScript libraries with TypeScript.
  • TypeScript supports both dynamic and static typing. It provides classes, visibility scopes, interfaces, and other features.
  • It has built-in support for ES6 modules and packages, so you do not have to worry about using them.
  • It comes with comprehensive tooling such as compiler errors and linting tools.
  • TypeScript files are automatically imported when referenced by another file, which helps ensure that all variables used within them have been declared.
