I'm going to be honest, I'm a backend developer and I've never written a tree in production. I understand the structure, I've written them for practice, but for real world code it's just never come up. It seems that for the overwhelming majority of developer roles these data structures are outsourced to a database, which is usually closer to the data than my service anyway. It's not that this knowledge is irrelevant, but there are so many aspects of writing, and maintaining, business logic with a team of others that are skipped entirely.
