Service Workers vs Local Storage: Which to Use?

What are the main differences between service workers and local storage?

When should I use service workers instead of local storage?

Use service workers when you need to manage caching, handle network requests, or enable offline functionality. Local storage is best for simple data storage needs.

Can I use both service workers and local storage together?

Yes, you can use both together! Service workers can cache resources while local storage can be used to store user preferences or session data.
