Example 1

import type {LiteralToPrimitive} from 'type-fest';

// No overloads needed to get the correct return type
function plus<T extends number | bigint | string>(x: T, y: T): LiteralToPrimitive<T> {
	return x + (y as any);
}

plus('a', 'b'); // string
plus(1, 2); // number
plus(1n, 2n); // bigint
definition: T extends number ? number : T extends bigint ? bigint : T extends string ? string : T extends boolean ? boolean : T extends symbol ? symbol : T extends null ? null : T extends undefined ? undefined : never
