Javascript DataView getBigInt64()

Introduction

The Javascript DataView getBigInt64() method gets a signed 64-bit integer at the specified byte offset from the DataView.

The return value is a BigInt. 

dataview.getBigInt64(byteOffset [, littleEndian])
  • byteOffset - the offset, in bytes, from the start of the view to read the data from.
  • 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 getBigInt64 method 

var buffer = new ArrayBuffer(8);
var dataview = new DataView(buffer);
let a = dataview.getBigInt64(0); 
console.log(a);
