The Reflect namespace object contains static methods for invoking interceptable JavaScript object internal methods. The methods are the same as those of proxy handlers.

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

The TypedArray.BYTES_PER_ELEMENT static data property represents the size in bytes of each element in a typed array.

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 __defineGetter__() method of Object instances binds an object's property to a function to be called when that property is looked up.

The subarray() method of TypedArray instances returns a new typed array on the same ArrayBuffer store and with the same element types as for this typed array. The begin offset is inclusive and the end offset is exclusive.

The toString() method of TypedArray instances returns a string representing the specified typed array and its elements. This method has the same algorithm as Array.prototype.toString().

The lastIndexOf() method of TypedArray instances returns the last index at which a given element can be found in the typed array, or -1 if it is not present. The typed array is searched backwards, starting at fromIndex. This method has the same algorithm as Array.prototype.lastIndexOf().

The slice() method of TypedArray instances returns a copy of a portion of a typed array into a new typed array object selected from start to end (end not included) where start and end represent the index of items in that typed array. The original typed array will not be modified. This method has the same algorithm as Array.prototype.slice().

The find() method of TypedArray instances returns the first element in the provided typed array that satisfies the provided testing function. If no values satisfy the testing function, undefined is returned. This method has the same algorithm as Array.prototype.find().
