Type Alias BoolEq<A, B>

BoolEq: TypeEq<A, true> extends true
    ? TypeEq<B, true> extends true
        ? true
        : TypeEq<B, false> extends true ? false : never
    : TypeEq<A, false> extends true
        ? TypeEq<B, true> extends true
            ? false
            : TypeEq<B, false> extends true ? true : never
        : never

Performs a logical equality (XNOR) operation on two boolean literal types A and B. Returns true if both A and B are the same, false otherwise.

Type Parameters

A extends boolean
The first boolean literal type (true or false).
B extends boolean
The second boolean literal type (true or false).

Example

type T_T = BoolEq<true, true>;   // true
type T_F = BoolEq<true, false>;  // false
type F_T = BoolEq<false, true>;  // false
type F_F = BoolEq<false, false>; // true
