# Javascript Loop For Of

## The For/Of Loop

The JavaScript `for/of` statement loops through the values of an iterable object.

`for/of`Мэдээлэлд зориулсан JavaScript нь давтагдах объектын утгыг давтана.

It lets you loop over iterable data structures such as Arrays, Strings, Maps, NodeLists, and more:

Энэ нь багц, үг, газрын зураг, зангилаа жагсаалт гэх мэт давтагдах өгөгдлийн бүтцийг давтах боломжийг танд олгоно.

### Syntax Синтакс

      `for (variable of iterable) {
  // code block to be executed
}`

**variable** – For every iteration the value of the next property is assigned to the variable. *Variable* can be declared with `const`, `let`, or `var`.

хувьсагч – Давталт бүрт дараагийн өмчийн утгыг хувьсагчид хуваарилна. Хувьсагчийг const, let, эсвэл var гэж зарлаж болно.

**iterable** – An object that has iterable properties.

**iterable** – Давтагдах шинж чанартай объект.

## Looping over an Array

## Багц дээр гогцоо хийх

       `let cars = ["BMW", "Volvo", "Mini"];
let text = "";

for (let x of cars) {
  text += x + "<br>";
}`

## Looping over a String

## Үгийг давтах

### Example Жишээ

      `let language = "JavaScript";
let text = "";

for (let x of language) {
text += x + "<br>";
}`

## The While Loop

The `while` loop and the `do/while` loop are explained in the next chapter.

While `while` ба `do/while` давталтыг дараагийн бүлэгт тайлбарлав.
