IS IT BETTER TO BE A JACK-OF-ALL-TRADES OR A MASTER-OF-ONE? (REDDIT THREAD)

Summary from the TLDR Web Dev newsletter

A Redditor asks if it's better to be a generalist or a specialist. The consensus is that it's best to be a “T-shaped” engineer, where you have general knowledge of a variety of subjects, but are specialized in a certain area. In general, developers should try to be as knowledgeable as possible while also trying to be the “expert” in certain areas on their team.
