+  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 }.
+includes: [propertyHelper.js, testTypedArray.js]
