Type alias Exclude<T, U, R>

🌪️ filter

Exclude from T those types that are assignable to U, and replace them with R.

This can be used as a drop-in replacement of the build-in Exclude.

Example

type R = Exclude<undefined, undefined> // never
type R = Exclude<undefined | 1, undefined> // 1

type R = Exclude<undefined, undefined, 2> // 2
type R = Exclude<undefined | 1, undefined, 2> // 1 | 2
