TypeScript?

A superset of JavaScript that adds functionality like static type-checking, interfaces and classes.

Compiles to JavaScript.

What problem does TypeScript solve?

With run-time type validation

Good ole JavaScript

Compile-time dopeness

Use case

Why?

• Structure
• Scale
• Real intellisense
• Declaration files
• Catch problems earlier

 

• All JavaScript is valid TypeScript!

TypeScript is a great tool, but not the absolute truth.

It's still just JavaScript

React + TypeScript

• JSX

Expressive components
