Introduction

The Javascript DataView getBigUint64() method gets an unsigned 64-bit integer at the specified byte offset from the DataView.

It returns a BigInt.

dataview.getBigUint64(byteOffset [, littleEndian])

• byteOffset - the offset in bytes from the start of the view.
• littleEndian - Optional, indicates whether the 64-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is read.

Using the getBigUint64 method

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
let a = dataview.getBigUint64(0); 
console.log(a);/*from   ww  w. j a  va2s.c  o m*/
