react, vite, github pages

What did you find difficult while building the project? I encountered an issue while attempting to add an event listener in the filter section. I invested several hours into figuring out how to modify the state in the application and resolve the problem.

Which areas of your code are you unsure of? I created component Checkbox and import them to all necessary components to type input and todo items. But don't sure this best way, cuz when i change state from true to false, all component rerender

Do you have any questions about best practices? I will be grateful for help and feedback
