{{alias}}( object, predicate[, thisArg ] )
    Tests whether at least one own property of an object passes a
    test implemented by a predicate function.

    The predicate function is provided three arguments:

    - value: property value.
    - index: property key.
    - object: the input object.

    The function immediately returns upon encountering a truthy return
    value.

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

    Parameters
    ----------
    object: Object
        Input object.

    predicate: Function
        Test function.

    thisArg: any (optional)
        Execution context.

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

    Examples
    --------
    > function positive( v ) { return ( v > 0 ); };
    > var obj = { 'a': -1, 'b': 2, 'c': -3 };
    > var bool = {{alias}}( obj, positive )
    true
