 ### functions
 
-Returns an array of function property names from own enumerable properties of object.
+Returns an array of function property names from own (and optionally inherited) enumerable properties of an object.
 
-Use `Object.keys(obj)` to iterate over the object's own properties, `Array.filter()` to keep only those that are functions.
+Use `Object.keys(obj)` to iterate over the object's own properties.
+If `inherited` is `true`, use `Object.get.PrototypeOf(obj)` to also get the object's inherited properties.
+Use `Array.filter()` to keep only those properties that are functions.
+Omit the second argument, `inherited`, to not include inherited properties by default.
