Where can user changes be stored?

Question

JavaScript

Good afternoon! I wanted to ask where you can store user actions? In addition to the database!
I tried to store it in a variable, but only one action is stored there, and I need at least 10, are there options other than how to save it in the database?

Answer 1

DB or file, this is what is stored in ROM.
Attempting to write to an array or object will result in data loss.
Actually, the question is old. Your variables live while the application lives.
