Typescript vs JavaScript: Which Is Better?

In this article, we will explain the differences between TypeScript and JavaScript and discuss when to use each.

Should we use TypeScript or JavaScript? People think about this when they start new web or Node.js projects, but it's also essential for projects that already exist.

TypeScript is like a fancy version of JavaScript. It has all the good things from JavaScript and some extra cool stuff.

TypeScript tries to make coding easier. It encourages us to write neat code, which can help make the code more prominent and better, but it might mean writing more code.

In this article, we will explain the differences between TypeScript and JavaScript and discuss when to use each.

What Is JavaScript?

JavaScript is a scripting language for interactive web pages running in web browsers. It can be used with technologies like XML and REST APIs. Originally meant as a supplementary language, it could be better for large apps designed for shorter code.

Features of JavaScript include:

  • Flexibility, dynamism, and cross-platform compatibility
  • Usability for both client-side and server-side development
  • Lightweight and interpreted
  • Support by all browsers
  • Weakly typed
  • JIT compilation

What Is Typescript?

TypeScript, developed and maintained by Microsoft, is an open-source, object-oriented programming language that superset JavaScript with optional typing. It compiles plain JavaScript and can be used for client-side and server-side applications. TypeScript supports dynamic and static typing, providing various features such as classes, interfaces, and functions. It can be executed on Node.js or any browser supporting ECMAScript 3 or later versions.

What Are the Differences Between Typescript and JavaScript?

In TypeScript vs JavaScript comparison, all JavaScript code is valid in TypeScript, making TypeScript a superset of JavaScript.

In simple terms, JavaScript + extra features = TypeScript


TypeScript JavaScript
Fewer production problems and bugs Reduce the number of error messages during development
Write more code Write less code
Compiled Interpreted
Easily guess how your program will work Difficult
Static Dynamic

So, if you save a JavaScript file (.js) as a TypeScript file (.ts), it will run smoothly. However, remember that TypeScript and JavaScript are not identical languages.

Why Did They Make Typescript When We Already Have JavaScript?

JavaScript language was first used for making websites look cool. But then people realized it could also do more complicated stuff on the websites. However, the JavaScript code got really hard and too much to handle. So, it couldn't do everything people wanted it to do like other fancy programming languages. That's why TypeScript was made to fix this problem.

When to Choose: Typescript vs JavaScript?

If you are working on a big project with many people, it's a good idea to use TypeScript. It can help prevent mistakes and make sure your code is safe. Also, if you use outside libraries and frameworks that offer type definitions, TypeScript can make it easier to write your code. On the other hand, if you want to write a quick script or a personal project, JavaScript might be a better choice.

When Should You Use Typescript?

  • Working on a big project, aiming for fewer mistakes.
  • Using libraries with type definitions for easier coding.
  • Have time to learn and use TypeScript.

When Should You Use JavaScript?

  • Writing a quick script or personal project, avoiding extensive code.
  • Preferring quick project development over long-term error prevention.
  • No prior knowledge of TypeScript and no time to learn it now.
