The copyWithin() method of TypedArray instances shallow copies part of this typed array to another location in the same typed array and returns this typed array without modifying its length. This method has the same algorithm as Array.prototype.copyWithin().

The TypedArray[@@species] static accessor property returns the constructor used to construct return values from typed array methods.

The Math namespace object contains static properties and methods for mathematical constants and functions.

The Function() constructor creates Function objects. Calling the constructor directly can create functions dynamically, but suffers from security and similar (but far less significant) performance issues as eval(). However, unlike eval (which may have access to the local scope), the Function constructor creates functions which execute in the global scope only.

The Reflect.getOwnPropertyDescriptor() static method is like Object.getOwnPropertyDescriptor(). It returns a property descriptor of the given property if it exists on the object, undefined otherwise.

The Proxy() constructor creates Proxy objects.

The Reflect.get() static method is like the property accessor syntax, but as a function.

The slice() method of ArrayBuffer instances returns a new ArrayBuffer whose contents are a copy of this ArrayBuffer's bytes from start, inclusive, up to end, exclusive. If either start or end is negative, it refers to an index from the end of the array, as opposed to from the beginning.

The Object.values() static method returns an array of a given object's own enumerable string-keyed property values.

The getFullYear() method of Date instances returns the year for this date according to local time.
