{{alias}}( value, constructor )
    Tests whether a value has in its prototype chain a specified constructor as
    a prototype property.

    While the prototype of an `object` created using object literal notion is
    `undefined`, the function returns `true` when provided an `object` literal
    and the `Object` constructor. This maintains consistent behavior with the
    `instanceof` operator.

    Parameters
    ----------
    value: any
        Input value.

    constructor: Function
        Constructor.

    Returns
    -------
    bool: boolean
        Boolean indicating if a value is an instance of a provided constructor.

    Examples
    --------
    > var bool = {{alias}}( [], Array )
    true
    > bool = {{alias}}( {}, Object )
    true
    > bool = {{alias}}( null, Object )
    false
