| 17 ECMAScript Standard Built-in Objects: |
| Every built-in Function object, including constructors, has a length |
| property whose value is an integer. Unless otherwise specified, this |
| value is equal to the largest number of named arguments shown in the |
| subclause headings for the function description, including optional |
| parameters. However, rest parameters shown using the form “...name” |
| are not included in the default argument count. |
| |
| Unless otherwise specified, the length property of a built-in Function |
| object has the attributes { [[Writable]]: false, [[Enumerable]]: false, |
| [[Configurable]]: true }. |
