How do I fix the 'React is not defined' error?

This error usually occurs when React is not imported in your component file. Make sure to add import React from 'react'; at the top.

What if I already have that import?

If you have the import statement, check if your React version is compatible with your code. Sometimes, using an outdated version can cause issues.

I see. What about the 'Cannot read property of undefined' error?

This error often happens when you're trying to access a property of an object that hasn't been initialized. Ensure that the object is defined before accessing its properties.

Thanks! Any tips for debugging in React?

Use React Developer Tools for Chrome or Firefox. They provide a great way to inspect your component hierarchy and state.
