There are thousands of materials on how to learn the basics of front-end: HTML, CSS, JS, responsiveness, some front-end library like Bootstrap and JS framework like React. The stuff that you need to land a front-end job; in fact I learned all that and I got a job myself, great!
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hard in the edge case of front-end development since it moves so fast and a book from 2016 is already pretty much outdated today.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?
And blogs. Read web dev blogs. Much more up to date than books, and you get to see the latest ideas and take part in discussions of evolving standards. My favs: A List Apart, Adactio, Smashing Magazine, CSS-Tricks, Zeldman, Stuff & Nonsense, The Web Ahead, Mozilla Hacks, Coding Horror.
