How do I fix React PropTypes errors?

I'm getting PropTypes errors in my React app. How can I fix them?

PropTypes errors usually indicate that the props being passed to a component don't match the expected types. Can you share the specific error message you're seeing?

It says that the prop 'age' is expected to be a number, but I'm passing a string.

You can fix this by ensuring that the value you pass for 'age' is a number. You might need to convert it using parseInt() or parseFloat() if it's coming from user input.

Got it! What if I want to make 'age' optional?

You can make 'age' optional by using PropTypes.number with .isRequired removed. It would look like this: age: PropTypes.number.
