The third age of JS is going to be really exciting. People treat JS-land as something that has a first class language that can build major production tools and applications. Cloud providers support JS for nearly all aspects of their large platforms. The one place where I anecdotally see a decrease is in full-stack JS apps, but that's because the entire premise of a singular back-end app is under scrutiny by the cloud ecosystem itself. JS just never had a chance to get more established as a back-end language before that happened.
