Int16Array

BaselineWidely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.

TheInt16Array typed array represents an array of 16-bit signed integers in the platform byte order. If control over byte order is needed, useDataView instead. The contents are initialized to0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

Int16Array is a subclass of the hiddenTypedArray class.

Constructor

Int16Array(): Creates a newInt16Array object.

Static properties

Also inherits static properties from its parentTypedArray.

Int16Array.BYTES_PER_ELEMENT: Returns a number value of the element size.2 in the case ofInt16Array.

Static methods

Inherits static methods from its parentTypedArray.

Instance properties

Also inherits instance properties from its parentTypedArray.

These properties are defined onInt16Array.prototype and shared by allInt16Array instances.

Int16Array.prototype.BYTES_PER_ELEMENT: Returns a number value of the element size.2 in the case of aInt16Array.
Int16Array.prototype.constructor: The constructor function that created the instance object. ForInt16Array instances, the initial value is theInt16Array constructor.
