{{alias}}( x, predicate[, thisArg] )
    Tests whether at least one element in an array passes a test implemented by
    a predicate function, while iterating from right to left.

    The predicate function is provided three arguments:

    - value: current array element.
    - index: current array element index.
    - arr: the input array.

    The function performs a linear scan and returns immediately upon
    encountering a truthy return value.

    If provided an empty array, the function returns `false`.

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

    predicate: Function
        Predicate function.

    thisArg: any (optional)
        Execution context.

    Returns
    -------
    bool: boolean
        The function returns `true` if the predicate function returns a truthy
        value for at least one element; otherwise, the function returns `false`.

    Examples
    --------
    > function f( v ) { return ( v > 0 ); };
    > var x = [ 0, 0, 1, 0 ];
    > var out = {{alias}}( x, f )
    true
