Javascript Int32Array entries()

Introduction

The Javascript Int32Array entries() method returns an iterator object that contains the key/value pairs for each index in the array. 

arr.entries()

Iteration using for...of loop 

var arr = new Int32Array([10, 20, 30, 40, 50]);
var eArray = arr.entries();

for (let n of eArray) {
  console.log(n);//  w ww  .j  a v  a 2s.c o m
}

Alternative iteration 

var arr = new Int32Array([10, 20, 30, 40, 50]);
var eArr = arr.entries();
console.log(eArr.next().value); // [0, 10]
console.log(eArr.next().value); // [1, 20]
console.log(eArr.next().value); // [2, 30]
console.log(eArr.next().value); // [3, 40]
console.log(eArr.next().value); // [4, 50]
