Yeah, I spent years in Java and then even longer in .NET and it felt like everything I was getting a bit fed up of in those worlds had invaded JS. 20 years ago I could never have imagined defending JS as a language but, as time wore on, I started to appreciate its more stripped back syntax. And then a lot of what’s been added in later ES standards has been great so it seems even more unnecessary to layer TS on top.
It took me a while to appreciate JS too. Thought it was just the beginner language until I used it. Also had to learn the hard way that a web backend is hard to do efficiently without an event loop.
