easy to update and modify - Because the rules only apply to the changed code. - Can get the fast feedback - Cons - Can sometimes be slow on the local machine - Sometimes new and old rule versions get mixed, causing inconsistencies - CI - Pros - Ensures all code follows the same rules - Linting can’t be skipped manually - Cons - Can sometimes be slow during CI runs - Rules are not as easy to update and modify - Because we need to apply rules to all code

They’re fast because they’re written in Go or Rust.

It might feel strange, but we can achieve our goal with it.

That means you’ll need to update all the code, which can take a long time.

Also, if team members have agreed to the team’s rules, they generally don’t skip it, although the situation might be different in open source projects.
