Please hear me out. I used to scoff at people who asked this question because client-side hashing is "so obviously wrong." I have read similar questions on this site but haven't found a satisfactory answer.
Why hash on the server instead of the client?
If the goal is to prevent someone with access to the password database from logging in, then server-side hashing is an absolute must (otherwise someone could just send to the server whatever they stole from the passwords database).
However, my understanding is that the purpose of hashing is to help people who share the same password across many sites. When a password is properly hashed & salted, an attacker cannot as easily brute force the plaintext password then try it on a bunch of other websites.
If mitigating password-reuse attacks is the goal, apart from clients having less hashing power, hashing & salting  on the client side makes sense because it means that even a fully compromised server would never see a client's plaintext password.
What am I missing?
 salting is important so that a compromised server cannot re-use hashes to log into other services hashing passwords on the client
