{{alias}}( value )
    Returns an array of an object's own enumerable property names.

    Name order is not guaranteed, as object key enumeration is not specified
    according to the ECMAScript specification. In practice, however, most
    engines use insertion order to sort an object's keys, thus allowing for
    deterministic extraction.

    If provided `null` or `undefined`, the function returns an empty array.

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

    Returns
    -------
    keys: Array
        List of an object's own enumerable property names.

    Examples
    --------
    > function Foo() { this.beep = 'boop'; return this; };
    > Foo.prototype.foo = 'bar';
    > var obj = new Foo();
    > var keys = {{alias}}( obj )
    [ 'beep' ]
