When should I use pcall?
I get how pcall works, but I don’t get when I should use it.

Use PCalls to handle things that could possibly error, such as datastores or Http requests, or if you're finding code doesn't work, you could do something like:
1 | local success, err = ypcall(function() |
2 | ppppppppppprint("i error!") |
3 | end) |
4 | if not success then |
5 | print("Oops! I errored: " .. err) |
6 | else |
7 | print("I succeeded!") |
8 | end |

This is a good tool for code errors, it is a good ally of a function if you want to keep track of what went wrong, you can use pcalls to keep track of your code carefully, putting one at each important step.
