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

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

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

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

    Returns
    -------
    props: Array
        List of an object's own writable properties.

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