| description: Length of IteratorPrototype[ @@iterator ] |
| info: | |
| ES6 Section 17: |
| 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. |
| |
| [...] |
| |
| Unless otherwise specified, the length property of a built-in Function |
| object has the attributes { [[Writable]]: false, [[Enumerable]]: false, |
| [[Configurable]]: true }. |
| features: [Symbol.iterator] |
