Exclude<T, U>
Constructs a type by excluding from T all union members assignable to U.
Syntax
Exclude<UnionType, ExcludedMembers>Returns
union type — The union T with every member assignable to U removed.
Examples
type T = 'a' | 'b' | 'c';
type Result = Exclude<T, 'a'>; // 'b' | 'c'
type NonFn = Exclude<string | number | (() => void), Function>;
// string | number
Notes
Defined as a distributive conditional type:
`T extends U ? never : T`. Operates on each union member individually. Use
`Omit` to drop object keys and `Extract` for the complementary operation.
