The real advantage of linters is that code comprehension becomes easier and authoring that code becomes simpler. The code always follows the same style in every project that team has, and everyone can configure the linter to reformat on save. It also completely removes the conversation on style from code reviews.
Haven’t you ever gotten a big PR from someone because their editor settings were different and they auto formatted a file differently than it was written before? This makes PRs a nightmare to differentiate between style and substantive changes.
The auto formatting is honestly one of the biggest productivity gains as a developer that I’ve seen. No longer do you have to ensure your code is indented when typing. A lot of times, I will even write multiple lines of code on a single line and let the formatter take over. And the end result is that my code is consistent and matches the style of all the surrounding code. It takes a cognitive burden off of everyone, when writing the code and when reading it (PR or otherwise).
