Useful types to hack around

prettify.ts

// prettify intersection on types, like `a & b & c`
type Prettify<T> = {[K in keyof T]: T[K]} & {};

// autocomplete that also accepts string
// so you still have intellisense but it's open to any string
type AutoComplete<T extends string> = T | (string & {});

// the value of objects
type ValueOf<T extends object> = T[keyof T];
