The annoyingly self-perpetuating truth: - There are a lot of JS devs available to hire - The ecosystem is huge and generally up to date (although you may have to bounce to a new framework for the same task a year later) - New tools like TypeScript allow you to keep making the JS choice with a cleaner conscience even though it’s just transpiled back into vanilla JS. - The mainstream alternatives are either not as fast to write or aren’t generally as performant as Node.
