How do I use the onUpdated hook in my React app?

How do I use the onUpdated hook in my React app?

The onUpdated hook is used to perform side effects in your component when it updates. You can use it like this:

import { useEffect } from 'react';

function MyComponent({ prop }) {
    useEffect(() => {
        // Your side effect code here
    }, [prop]); // Dependency array
}

What kind of side effects can I handle with it?

You can handle various side effects like fetching data, updating the DOM, or subscribing to events. Just ensure to clean up any subscriptions or listeners in the return function of useEffect.

Can I use multiple onUpdated hooks in one component?

Yes, you can use multiple useEffect hooks in a single component. Each can handle different side effects based on their own dependencies.

What happens if I don't provide a dependency array?

If you don't provide a dependency array, the effect will run after every render, which can lead to performance issues.
