Typescript Cheatsheet: Type

Alain Chautard TypeScript

A few months back, I shared a cheat sheet for Typescript Control Flow. Today, I want to share a cheat sheet on types, which are the main reason why Typescript is so useful.

A few interesting features that aren’t too well known:

  • The keyof operator and the Type[Property] illustrated in the Mapped Types section
  • One of my favorites: Union types and the even more powerful Template Union Types (bottom right corner of the cheat sheet)
