# 2.5.1 forEach 메소드

ES5부터 `Array.prototype.forEach` 메소드가 추가되었다. 이 메소드는 배열의 원소를 인자로 받는 콜백 함수를 인자로 받아, 배열 내의 각 원소에 대해 해당 콜백을 실행한다.

```javascript
langs.forEach(lang => {
  console.log(lang);
}
```

`forEach` 메소드는 간결하지만, 반복문 중간에 `break` 혹은 `return` 등을 사용해 **실행 흐름을 제어할 수 없다**는 단점을 갖고 있다.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://ahnheejong.gitbook.io/ts-for-jsdev/02-ecmascript/element-enumeration/foreach.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
