{{alias}}( x, mask )
    Returns a new array by applying a mask to a provided input array.

    If a mask array element is falsy, the corresponding element in `x` is
    included in the output array; otherwise, the corresponding element in `x` is
    "masked" and thus excluded from the output array.

    Parameters
    ----------
    x: Array|TypedArray|Object
        Input array.

    mask: Array|TypedArray|Object
        Mask array.

    Returns
    -------
    out: Array|TypedArray|Object
        Output array.

    Examples
    --------
    > var x = [ 1, 2, 3, 4 ];
    > var y = {{alias}}( x, [ 0, 1, 0, 1 ] )
    [ 1, 3 ]
