But where to go from here? I take it that most people become better by learning from their seniors at work, but I work for a small company and unfortunately I don't have any very experienced front-end developer around to learn from, yet at the same time I know that my skills aren't great and there's a lot I still must learn. Googling for "learn front-end" just gives me a ton of materials on how to learn the basics: the stuff I already know. I thought I should turn to books to find more in-depth knowledge, but that's particularly hard in the edge case of front-end development since it moves so fast and a book from 2016 is already pretty much outdated today.
I'm thinking it would be great if there were experienced front-end devs who streamed live coding sessions, or some complex open source front-end projects that one could hack into and also see good front-end code that they should emulate, but I couldn't find anything like that for front-end.
So my question is how do I learn it beyond the basics?
