What are the best practices for caching in JavaScript?
Caching in JavaScript can significantly improve performance. Key practices include using localStorage, sessionStorage, and IndexedDB for client-side caching, and implementing service workers for offline capabilities.
Can you explain how service workers help with caching?
Service workers act as a proxy between your web app and the network. They can intercept network requests and serve cached responses, allowing for faster load times and offline access.
What are the differences between localStorage and sessionStorage?
localStorage persists data even after the browser is closed, while sessionStorage only keeps data for the duration of the page session.
Are there any libraries you recommend for caching?
Yes, libraries like Workbox can simplify service worker implementation, and libraries like Axios have built-in caching mechanisms.
