TS2420 — Class Incorrectly Implements Interface

이 에러의 원인

The class is missing one or more properties or methods required by the interface. The implements clause enforces that the class provides all members declared in the interface.

수정 방법

Add all missing properties and methods from the interface. Ensure the types of implemented members match the interface. Use an IDE to auto-implement interface members.

interface Animal { speak(): void }
class Dog implements Animal {}
