As your project grows and you add more and more dependencies, it can become hard to remember why you have any given dependency. This can lead to you having multiple ways of doing the same task or keeping a library around that you don't actually need anymore.
One way to combat this is with comments.
deps.edn.Exactly what comments to put is more art than science, but aiming to keep it short and sweet is a decent strategy.
Some things don't deserve a special note, of course. You won't need to later figure out
why org.clojure/clojure is there.
Some things definitely do. For better or worse, we got some silly names out there.
