String.prototype.toString()

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2015년 7월.

toString() 메서드는 객체의 문자열 표현을 반환합니다.

In this article

시도해 보기

const stringObj = new String("foo"); console.log(stringObj); // Expected output: String { "foo" } console.log(stringObj.toString()); // Expected output: "foo"

구문

js
toString();

반환 값

메서드를 호출하는 객체의 문자열 표현.

설명

String 객체는 Object 객체의 toString() 메서드를 상속하지 않고 재정의합니다. String 의 toString() 메서드는 객체의 문자열 표현을 반환하며 String.prototype.valueOf() 메서드와 동일합니다.

예제

toString() 사용하기

String 객체의 문자열 값을 표시하는 예제입니다.

js
var x = new String("Hello world"); console.log(x.toString()); // logs 'Hello world'

명세
