A guide to understanding TypeScript’s basic type system and writing bug-resistant code

Automatically translated from Japanese. See the Japanese original for the original wording.

TypeScript is a language that adds static typing to JavaScript.

Why TypeScript

With types, you can find errors while you’re still writing the code.

Basic Types

typescript
const name: string = "Disnana";
const age: number = 25;
const isActive: boolean = true;

Thanks to type inference, in many cases you don’t need to write types explicitly.
