Love it! And I love javascript; I taught it to myself about 8 years ago because I got sick of just doing Android development with Java and wanted to be able to code apps for iOS too. Never thought I would be doing it for front-end and back-end development now.
The most complicated part I have found is getting good at using functions. I spend probably too much time using Ramda to remove any need for writing imperative loops. It's so great when it works, but still takes me a lot of time to get to that point.
