TypeScript is a typed superset of JavaScript created by Microsoft that adds optional types, classes

and many other features, and compiles to plain JavaScript. Angular is built entirely in TypeScript and it is used as the primary language there. You can install it globally as

bash
1npm install -g typescript

Let's see a simple example of TypeScript usage,

typescript
1function greeting(name: string): string {
2  return "Hello, " + name;
3  }
4
5let user = "Sudheer";
6
7console.log(greeting(user));

The greeting method allows only string type as argument.
