{{alias}}( value[, level] )
Returns an array of an object's inherited enumerable and non-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.
level: integer (optional)
Inheritance level.
Returns
-------
keys: Array
List of an object's inherited enumerable and non-enumerable property
names.
Examples
--------
> var keys = {{alias}}( [] )
