Javascript Calculator - support for React Hooks?

Hello there,

The test suite does support all React 17 features - hooks included.

We are investigating an issue with React 18:

I have edited this issue. Code that is passing using React 17 is failing with… React 18. It seems to be an issue with the new batch rendering and our tests. At this time, I'm not sure what the best solution is. I haven't really looked into it much. ### Affected Page * Random Quote Machine * The fCC example is using jQuery, I tested it with React 18 and it worked just fine. * Markdown Previewer * Works * JavaScript Calculator * 9/16 passed * Example - https://codepen.io/lasjorg/pen/JjpRybg * 25 + 5 Clock * 13/29 passed (The test is no longer able to manipulate the timer so it is slow to test) * Example - https://codepen.io/lasjorg/pen/WNMGEOM * Drum Machine * 7/8 passed * Example - https://codepen.io/lasjorg/pen/jOZrXGv Tests: https://github.com/freeCodeCamp/testable-projects-fcc/blob/main/src/project-tests/ ### Additional context Forum threads: https://forum.freecodecamp.org/t/drum-machine-test-7-is-failing/507800/ https://forum.freecodecamp.org/t/stuck-on-drum-machine-test-7/508120/ https://forum.freecodecamp.org/t/25-5-clock-pomodoro-timer-not-passing-test-12-decrease-break-time/504446/12 https://forum.freecodecamp.org/t/my-tests-don-t-make-sense-in-my-25-5-clock/504936

If you are using React 18, I suggest you downgrade.

Hope this helps
