How do IndexedDB and LocalStorage compare in performance?

IndexedDB generally offers better performance for larger datasets compared to LocalStorage. It supports asynchronous operations, which means it won't block the main thread, making it more efficient for complex queries.

What are the main differences in their storage limits?

LocalStorage typically has a limit of about 5-10MB per origin, while IndexedDB can store significantly more data, often in the hundreds of megabytes or even gigabytes, depending on the browser.

Is IndexedDB more complex to use than LocalStorage?

Yes, IndexedDB has a more complex API and requires more setup than LocalStorage, which is simpler and more straightforward for basic key-value storage.

When should I choose IndexedDB over LocalStorage?

You should choose IndexedDB when you need to store large amounts of data, require complex queries, or need to handle transactions. LocalStorage is better for simpler, smaller data needs.
