Javascript Int32Array [@@iterator]()

Introduction

The initial value of the @@iterator property is the same as the initial value of the values() property. 

arr[Symbol.iterator]()

Iteration using for...of loop 

var arr = new Int32Array([10, 20, 30, 40, 50]);
for (let n of arr) {
  console.log(n);//from   ww w . j  a va 2  s . c om
}

Alternative iteration 

var arr = new Int32Array([10, 20, 30, 40, 50]);
var eArr = arr[Symbol.iterator]();
console.log(eArr.next().value); // 10
console.log(eArr.next().value); // 20
console.log(eArr.next().value); // 30
console.log(eArr.next().value); // 40
console.log(eArr.next().value); // 50
