Javascript DataView setUint16()

Introduction

The Javascript DataView setUint16() method stores an unsigned 16-bit integer value at the specified offset to the DataView. 

dataview.setUint16(byteOffset, value [, littleEndian])
  • byteOffset - the offset, in byte, from the start of the view.
  • value - the value to set.
  • littleEndian - Optional, boolean value. If false or undefined, a big-endian value is written. Otherwise use the little endian.

Using the setUint16 method 

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setUint16(1, 3);//from   w w w .  ja  va2s.c o  m
let a = dataview.getUint16(1);
console.log(a);// 3
