Boolean.prototype

Boolean.prototype 속성은 Boolean 생성자의 프로토타입을 나타냅니다.

Property attributes of Boolean.prototype
Writable no
Enumerable no
Configurable no

설명

Boolean 인스턴스는 Boolean.prototype을 상속받습니다. 생성자의 프로토타입 객체를 사용해 모든 Boolean 인스턴스에 속성이나 메서드를 추가할 수 있습니다.

속성

Boolean.prototype.constructor
인스턴스의 프로토타입을 생성한 함수를 반환합니다. 기본값은 Boolean 함수입니다.

메서드

Boolean.prototype.toSource()
Boolean 객체의 소스를 포함한 문자열을 반환합니다. 반환 문자열을 사용해 동일한 객체를 생성할 수 있습니다. Object.prototype.toSource() 메서드를 재정의합니다.
Boolean.prototype.toString()
객체의 값에 따라 문자열 "true" 또는 "false"를 반환합니다. Object.prototype.toString() 메서드를 재정의합니다.
Boolean.prototype.valueOf()
Boolean 객체의 원시 값을 반환합니다. Object.prototype.valueOf() 메서드를 재정의합니다.
