Description

Summary

The solution for the third challenge, "Fix debouncing," does not require a Ref. Moving the let timeoutID; to the top inside the DebouncedButton component will fix the debouncing. Either point this out in the explanation or make it re-render so the solution requires Ref.

https://react.dev/learn/referencing-values-with-refs

Details

Since code example does not use State, there's no re-rendering, and so there's no need to use Ref to remember anything across re-renders. The page mentions that Refs are not used often; although future-proof, I think the example should only use Ref when necessary.

Research direction

Start at the “Referencing Values with Refs” page and inspect the third challenge, “Fix debouncing,” including its explanation and solution. Done means the documentation explains why Ref is used, or the example is changed so re-rendering makes Ref necessary; verify the rendered page and challenge wording.
