The Int16Array typed array represents an array of 16-bit signed integers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0 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 hidden TypedArray class.
TypedArray
Int16Array()
Creates a new Int16Array object.
Also inherits static properties from its parent TypedArray.
Int16Array.BYTES_PER_ELEMENT
Returns a number value of the element size. 2 in the case of Int16Array.
2
Inherits static methods from its parent TypedArray.
Also inherits instance properties from its parent TypedArray.
These properties are defined on Int16Array.prototype and shared by all Int16Array instances.
Int16Array.prototype
Int16Array.prototype.BYTES_PER_ELEMENT
Returns a number value of the element size. 2 in the case of an Int16Array.
Int16Array.prototype.constructor
The constructor function that created the instance object. For Int16Array instances, the initial value is the Int16Array constructor.
Inherits instance methods from its parent TypedArray.
// From a length const int16 = new Int16Array(2); int16[0] = 42; console.log(int16[0]); // 42 console.log(int16.length); // 2 console.log(int16.BYTES_PER_ELEMENT); // 2 // From an array const x = new Int16Array([21, 31]); console.log(x[1]); // 31 // From another TypedArray const y = new Int16Array(x); console.log(y[0]); // 21 // From an ArrayBuffer const buffer = new ArrayBuffer(16); const z = new Int16Array(buffer, 2, 4); console.log(z.byteOffset); // 2 // From an iterable const iterable = (function* () { yield* [1, 2, 3]; })(); const int16FromIterable = new Int16Array(iterable); console.log(int16FromIterable); // Int16Array [1, 2, 3]
