Javascript DataView setBigUint64()

Introduction

The Javascript DataView setBigUint64() method stores an unsigned 64-bit integer value at the offset to the DataView. 

dataview.setBigUint64(byteOffset, value [, littleEndian])
  • byteOffset - the offset, in bytes, from the start of the view.
  • value - the value to set as a BigInt.
  • littleEndian - Optional, boolean value. If false or undefined, a big-endian value is written. Otherwise use the little endian.

Using the setBigUint64 method 

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
dataview.setBigUint64(0, 3n);/*  w  w  w.  ja  v a 2 s.c om*/
let a = dataview.getBigUint64(0);
console.log(a);
