TypeScript: A Powerful Alternative to JavaScript

TypeScript is a superset of JavaScript that adds optional static typing and other advanced features to make building large-scale applications easier and more efficient. It is designed to be compatible with existing JavaScript code, making it a powerful alternative to vanilla JavaScript for developers who want to improve their code quality and maintainability. TypeScript is open source, cross-platform, and is usually used for developing web and server-side applications.

Top companies using TypeScript:

  • Microsoft
  • Google
  • Asana
  • Slack
  • Airbnb
  • Lyft
  • Dropbox

TypeScript in your browser

The purpose of TypeScript is to enable developers to write scalable and maintainable applications. However, many developers want to try out/experiment with TypeScript, which can be a painful process as different versions need to be installed and setup locally.

Don't worry, we've got your back! Using codedamn's online TypeScript compiler, you can quickly code, collaborate, compile, run, and share TypeScript code for free. The TypeScript online compiler by codedamn is robust and feature-rich, running the latest version of TypeScript. Getting started is easy and fast since the editor shows sample boilerplate code. Feel free to add any packages you like by using the npm package manager in the integrated terminal. For example,

npm install express

What is happening under the hood?

TypeScript is transpiled (compiled to a different programming language) to JavaScript before it is executed, so it can run in any browser or Node.js runtime environment. This means that any code written in TypeScript can be used in a JavaScript project, and vice versa.

Codedamn TypeScript Compiler

The codedamn online compiler utilizes the power of cloud computing to give you a fast and reliable coding experience. When you boot the online TypeScript compiler, a docker container is started on a remote Linux computer. This docker container is already setup with the latest version of TypeScript, which can compile your code and check for any errors or problems. As your code is executed, the output/errors will show up on the integrated terminal of the online TypeScript compiler.

To define a function that takes a string argument and returns a boolean, you can use the following TypeScript code:

function isString(arg: any):boolean {   
	return typeof arg === "string"; 

Then you can use it like so:

if (isString("hello world")) {   
	console.log("It's a string!"); 
	} else { 
		console.log("It's not a string!");

Now, to execute your TypeScript code simply run the following command:

tsc index.ts && node index.js

🚨 Pro Tip!

Start your TypeScript compiler with ts-node-dev to avoid re-compiling and re-starting your server every time you make a change. Install ts-node-dev using npm or yarn:

npm install -g ts-node-dev

Start your compiler like so:

ts-node-dev --respawn index.ts
