React Local Storage

This snippet provides an introduction to using local storage with React, a popular JavaScript library for building user interfaces.

const [data, setData] = useState(localStorage.getItem('myData') || ''); useMemo(() => {localStorage.setItem('myData', data);}, [data]);

In this code snippet, we are defining a state variable 'data' that initially retrieves and stores data from the localStorage using the key 'myData'.

The useMemo hook is then used to set the localStorage with current state of 'data' whenever 'data' changes. This essentially stores user input data in the localStorage for that session.

By using localStorage in this manner with React, you can effectively persist user data across different browser sessions.
