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. 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 }.

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, this value is the name that
is given to the function in this specification. For functions that
are specified as properties of objects, the name value is the
property name string used to access the function. [...]
Unless otherwise specified, the name property of a built-in function
object, if it exists, has the attributes { [[Writable]]: false,
