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

    The predicate function is provided three arguments:

    - value: collection value.
    - index: collection index.
    - collection: the input collection.

    The function immediately returns upon encountering a truthy return value.

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

    Parameters
    ----------
    collection: Array|TypedArray|Object
        Input collection over which to iterate. If provided an object, the
        object must be array-like (excluding strings and functions).

    predicate: Function
        The test function.

    thisArg: any (optional)
        Execution context.

    Returns
    -------
    bool: boolean
        The function returns `true` if the predicate function returns `true` for
        any element; otherwise, the function returns `false`.

    Examples
    --------
    > function negative( v ) { return ( v < 0 ); };
    > var arr = [ -1, 1, 2, 3, 4 ];
    > var bool = {{alias}}( arr, negative )
    true
