+ BigInt ( value )
+
+ 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 }.
