Quick DevEx improvement
Use formatters and linters to quickly improve developer experience.
One quick way to improve DevEx, especially for a team, is to implement code formatting and linting into the CI/CD pipeline. And, ideally into the local development flow.
It's so nice to not worry about how to format the code. And to look at other code and have it look consistent.
Diffs are better because formatting in different styles isn't a change anymore.
Linting will catch and simplify many expressions. And enforce common coding styles.
Pick something that's not too strict and that covers most cases. Some of the team will disagree with some of the rules, but they'll get used to it quickly.
