TypeScript

Basic types are your first vocabulary in TypeScript.

They describe the shape of objects and let you reuse types across your project.

Typing parameters and return values documents your functions and prevents bugs.

They give a fixed, named set of values instead of magic numbers or strings.

They compose flexible types that describe real values more precisely.

TypeScript narrows types based on checks — learn to work with it, not against it.

Generics let you write reusable code while keeping type safety.

Built-in types that save time and reshape your types easily.

TypeScript supports object-oriented programming with powerful class tools.

Organizing code into typed modules keeps a project clear and scalable.

TypeScript with React gives you autocomplete and full component safety.

The tsconfig file controls compiler strictness and behavior in your project.

Declaration files provide types for JavaScript libraries that lack them.

Using TypeScript well separates clean code from code full of any.
