Web/JavaScript/Reference/Global objects/TypedArray/@@iterator

The initial value of the @@iterator property is the same function object as the initial value of the values property.

Syntax

arr[Symbol.iterator]()

Return value

The array iterator function, which is the values() function by default.

Examples

Iteration using for...of loop

var arr = new Uint8Array([10, 20, 30, 40, 50]);
// your browser must support for..of loop
// and let-scoped variables in for loops
for (let n of arr) {
  console.log(n);
}

Alternative iteration

var arr = new Uint8Array([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
