흔히 이렇게 알고 있다

A core-js-provided URL.prototype.toJSON dynamically calls the current URL.prototype.toString, so reassigning toString later also changes toJSON output.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• When the host URL.prototype.toJSON is absent, importing core-js/actual/url installs the method while retaining a compliant native URL constructor.
• The installed toJSON serializes an opaque mailto URL as mailto:sample-user and its pathname remains sample-user.
• After URL.prototype.toString is reassigned, String(url) observes the replacement but url.toJSON() still returns the original serialized URL.
