How to make an updating like btn in javascript?
I want to make an actual like button, when the page refreshes the number of likes is still there. I know I could use local storage but it will only work on my server not anyone else's. I want to find a way to achieve this using firebase storage, but Idk how. Can anyone guide me through this?

for upvotes that only work for may people live check this code out:

It uses firebase firestore(to store data), wich is free, but sadly has a limit
The only way to prevent users from posting more than one up-or downvote is by making accounts, they can use multiple account abuse, or use cookies/localstorage to store if they already upvoted, but they can clear cache or use ignocito mode
the other strategy is to use cookies/localstorage for storing upvotes, but data only applies for 1 user and is cleared when they clear cache or use ignocito mode
