Exclude

Exclude constructs a type by excluding from UnionType all union members that are assignable to ExcludedMembers.

type T0 = Exclude<"a" | "b" | "c", "a">;  // "b" | "c"
type T1 = Exclude<"a" | "b" | "c", "a" | "b">;  // "c"
type T2 = Exclude<string | number | (() => void), Function>;  // string | number
