A TypedArray object describes an array-like view of an underlying binary data buffer. There is no global property named TypedArray
, nor is there a directly visible TypedArray
constructor. Instead, there are a number of different global properties, whose values are typed array constructors for specific element types, listed below. On the following pages you will find common properties and methods that can be used with any typed array containing elements of any type.

Description
ECMAScript 2015 defines a TypedArray
constructor that serves as the [[Prototype]]
of all TypedArray
constructors. This constructor is not directly exposed: there is no global %TypedArray%
or TypedArray
property. It is only directly accessible through Object.getPrototypeOf(Int8Array)
and similar. All TypedArray
s constructors inherit common properties from the %TypedArray%
constructor function. Additionally, all typed array prototypes (TypedArray.
prototype
) have %TypedArray%.prototype
as their [[Prototype]]
.
The %TypedArray%
constructor on its own is not particularly useful. Calling it or using it in a new
expression will throw a TypeError
, except when used during object creation in JS engines that support subclassing. There are at present no such engines, so %TypedArray%
is only useful to polyfill functions or properties onto all TypedArray
constructors.
When creating an instance of a TypedArray
(e.g. Int8Array
), an array buffer is created internally in memory or, if an ArrayBuffer
object is given as constructor argument, then this is used instead. The buffer address is saved as an internal property of the instance and all the methods of %TypedArray%.prototype
, i.e. set value and get value etc., operate on that array buffer address.

Constructor
This object cannot be instantiated directly. Instead, you create an instance of an array of a particular type, such as a Int8Array
or a BigInt64Array
. These objects all have a common syntax for their constructors:
new TypedArray(); new TypedArray(length); new TypedArray(typedArray); new TypedArray(object); new TypedArray(buffer [, byteOffset [, length]]);
Where TypedArray is a constructor for one of the concrete types.
Parameters
length
- When called with a
length
argument, an internal array buffer is created in memory, of sizelength
multiplied byBYTES_PER_ELEMENT
bytes, containing zeros. typedArray
- When called with a
typedArray
argument, which can be an object of any of the typed array types (such asInt32Array
), thetypedArray
gets copied into a new typed array. Each value intypedArray
is converted to the corresponding type of the constructor before being copied into the new array. The length of the new typed array will be same as the length of thetypedArray
argument. object
- When called with an
object
argument, a new typed array is created as if by theTypedArray.from()
method. buffer
,byteOffset
,length
- When called with a
buffer
, and optionally abyteOffset
and alength
argument, a new typed array view is created that views the specifiedArrayBuffer
. ThebyteOffset
andlength
parameters specify the memory range that will be exposed by the typed array view. If both are omitted, all ofbuffer
is viewed; if onlylength
is omitted, the remainder ofbuffer
is viewed.

Examples
New is required
Starting with ECMAScript 2015, TypedArray
constructors must be constructed with the new
operator. Calling a TypedArray
constructor as a function without new
will throw a TypeError
.
var dv = Int8Array([1, 2, 3]); // TypeError: calling a builtin Int8Array constructor // without new is forbidden
var dv = new Int8Array([1, 2, 3]);
Property access
You can reference elements in the array using standard array index syntax (that is, using bracket notation). However, getting or setting indexed properties on typed arrays will not search in the prototype chain for this property, even when the indices are out of bound. Indexed properties will consult the ArrayBuffer
and will never look at object properties. You can still use named properties, just like with all objects.
// Setting and getting using standard array syntax var int16 = new Int16Array(2); int16[0] = 42; console.log(int16[0]); // 42 // Indexed properties on prototypes are not consulted (Fx 25) Int8Array.prototype[20] = 'foo'; (new Int8Array(32))[20]; // 0 // even when out of bound Int8Array.prototype[20] = 'foo'; (new Int8Array(8))[20]; // undefined // or with negative integers Int8Array.prototype[-1] = 'foo'; (new Int8Array(8))[-1]; // undefined // Named properties are allowed, though (Fx 30) Int8Array.prototype.foo = 'bar'; (new Int8Array(32)).foo; // "bar"
