I work in Front-End and have always had side-projects with coding involved (Games, Websites, CLI-Tools).
Some of my career's and company's circumstances (no senior front-end-devs for reviewing and mentoring around, mostly work on classic websites/web-shops) make it necessary. It's the only way to keep my skills somewhat up-to-date and to improve beyond what I do at work.
Coding and building is fun to me, so I was ok with this. After getting kids though, my available home-coding-time shrunk to almost zero.
My employer does allow and pay for conferences/workshops, but there's nothing as good for learning as a real project with more senior team-members, I guess.
I really don't want to leave after 8 years of building reputation and seniority, and start from scratch elsewhere, in a big unknown.
How do others cope with that?
