I got really into Node for a backend around 2015. I loved it, its execution was fast enough, I could speed through feature implementations, it was so much easier to build things compared to the 5 million line Java project from my previous employer. Then a not-so-competent team member joined and it made working in JS complete hell. I had to be so much more careful on code reviews because there was no compiler to catch common mistakes, and still issues slipped through. TypeScript is here now and that's great, it solves some of the issues I mentioned, but I moved on to Rust (and stopped doing web stuff for the most part) and I'll trade my implementation speed for easier code reviews and majorly reduced debugging time.
