How to create a Counter

hey guys, i have this project where user create a post and users can like a post, but now, i cant seem to be able to count the number of likes, it seem like Appwrite did not provide the option to actually count attribute or document

please guys, how do i do this??

For that the best way would be to move the counting up logic into a function
And, if you don't want same user like more than once, then you'll be best creating another collection named likes with relationship to the each post with unique key composed from user id and post id.
