  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.
  Optional parameters (which are indicated with brackets: [ ]) or rest parameters (which
  are 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 }.
