Math.log2 ( x )
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 }.
