+Returns an array of function property names from own and inherited enumerable properties of object.

+Use `Object.keys(obj)` and `Object.get.PrototypeOf(obj)` to iterate over the object's own and inherited properties, `Array.filter()` to keep only those that are functions.
+Use the spread operator (`...`) to combine all returned property names into one array.
