I've been working as a bona fide junior developer for almost 6 months now and I've got a reasonably good handle on the foundations of web dev stuff and know the big obvious things to learn.
But what are some useful but maybe lesser-known technologies worth looking into? One example I saw would be WebSockets which I only really noticed after seeing them in an interview task example. Another would be looking deeper into ES Modules and trying to understand how they actually work.
Love to hear what you think and recommend!
