TypeScript 4.3 has just introduced an override declaration:

https://devblogs.microsoft.com/typescript/announcing-typescript-4-3-beta/#override-and-the-noimplicitoverride-flag

The relationship of this new feature with @override needs to be documented.

The TypeScript feature does not subsume @override as this library supports plain JavaScript as well.

The README should be updated to explain the difference and why @override should still be used
