17 ECMAScript Standard Built-in Objects:
Every built-in Function object, including constructors, that is not
identified as an anonymous function has a name property whose value
is a String.
Unless otherwise specified, the name property of a built-in Function
object, if it exists, has the attributes { [[Writable]]: false,
[[Enumerable]]: false, [[Configurable]]: true }.
