Javascript Int8Array Type

Introduction

A Int8Array object describes an array-like view of an underlying binary data buffer.

The constructors are listed as follows:

new Int8Array();
new Int8Array(length);
new Int8Array(typedArray);
new Int8Array(object);
new Int8Array(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 Int8Array.`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 Int16Array(2);
int16[0] = 42;//  w  ww.  j  av a2  s . c  o  m
console.log(int16[0]); // 42

Type	Value Range	Size in bytes	Description	Equivalent C type
Int8Array	-128 to 127	1	8-bit two's complement signed integer	int8_t
