The culture doesn't exist in JavaScript land because historically it has been difficult to do. The tooling sucked. It is getting vastly better, but sadly, it will take effort to get back into the practice.

I hope that more people building the learning courses will focus on that. If I had time, I'd do one myself, as I now heavily test all my React stuff. I refuse to build another webapp without proper automated unit testing. It catches so much stuff.
