Javascript Int32Array Type

Introduction

A Int32Array object describes an array-like view of an underlying binary data buffer.

The constructors are listed as follows:

new Int32Array();
new Int32Array(length);
new Int32Array(typedArray);
new Int32Array(object);
new Int32Array(buffer [, byteOffset [, length]]);

Parameter	Optional	Meaning
length	Required	an internal array buffer is created of size `length` multiplied by BYTES_PER_ELEMENT bytes.
typedArray	Required	the typedArray is copied into a new typed array.
object	Required	use the Int32Array.`from()` method.
buffer	Required	create from buffer
byteOffset	optional	offset to start
length	optional	length to copy

Property access

You can reference elements in the array using standard array index syntax.

var int16 = new Int32Array(2);
int16[0] = 42;//w  ww .  j av a2  s . co  m
console.log(int16[0]); // 42
