--- Comment #1 from Joseph Pecoraro <joepeck at webkit.org> ---
In Safari Technology Preview array destructuring has improved greatly! However it is still considerably slower than normal array access: (~7x down from ~20x).

    [Log] Array - Normal - 2ms
    [Log] Array - Destructuring - 15ms
    [Log] Object - Normal - 1ms
    [Log] Object - Destructuring - 1ms
