TypeScript introduced a new flag called `noImplicitOverride` as part of TypeScript v4.3. This flag introduces a new keyword called `override` that can be applied to members which override declarations from a base class. This helps with code health as TS will report an error if e.g. the base class changes the method name but the override would still have the old method name. Similarly, if the base class removes the method completely, TS would complain that the memeber with `override` no longer overrides any method. A similar concept applies to abstract methods, with the exception that TypeScript's builtin `noImplicitOverride` option does not flag members which are implemented as part of an abstract class. We want to enforce this as a best-practice in the repository as adding `override` to such implemented members will cause TS to complain if an abstract member is removed, but still implemented by derived classes.
