can caches cause memory leak?

If I use cacheTime as Infinity, this can cause a memory leak on the app?

the cache is just an object in javascript. We distribute it via react context through the QueryClientProvider. Infinite CacheTime means we'll never remove it from the cache. So the data will stick around until you unmount your QueryClientProvider.

Usually, in a single page application, you'll only have one QueryClientProvider at the top of your App. So that cache entry will stick around for the lifetime of your app.

I'm not really sure what a "memory leak" would be for you?

@TkDodo Thank you for your answer. I meant with "memory leak", the data will be added every time to somewhere and its size will get bigger each time with our caches and blood out. But I understood with your answer it is just a Javascript object and its size can't get more prominent as I thought. So thank you I got my answer.
