        • Parameters

          • Rest...n: N

          Returns number

    Returns Vector

    The resulting vector.

    apply((a, b) => a + b, [1, 2, 3], [4, 5, 6]); // [5, 7, 9]
    
    apply((i) => i * 2, [1, 2, 3]); // [2, 4, 6]
    
    apply((a, b) => a + (b - a) / 2, [1, 2, 3], [4, 5, 6]); // [2.5, 3.5, 4.5]
