    Pattern Matching in Typescript

    Fast and efficient pattern matching in Typescript.

    test('early exit if the condition has met', () => {
      let executed = false;
      pattern<[number, number, number]>(1, 2, 3)
        .case(1, 2, 3)((a, b, c) => {return 1})
        .case(1, 2, 3)((a, b, c) => {executed = true; return 1})
        .match();
      expect(executed).toBe(false);
    });

    Fall-through

    The function next could be used as a placeholder to continue with the next statement.

    test('fall-through if the callback is not provided', () => {
      const result = pattern<[number, number, number]>(1, 2, 3)
        .case(1, 2, 3)(next)
        .case(1, 2, 3)((a, b, c) => {return 1})
        .match();
      expect(result).toBe(1);
    });

    Happy hacking!
