JS achieved critical mass especially with the advent of NodeJS; it'll be difficult for a competitor in the same space to take over.

But that's fine; JS is fine for what it's used for, i.e. browsers / webpages and at a stretch rich desktop UIs. I think the main issue that the author has is that for a lot of people it's become a golden hammer.

A few years ago I started applying for jobs again; what I found (but this might have been the recruiter) is that multiple companies were in the process of replacing their PHP backends with Javascript / NodeJS backends. I couldn't fathom why people were starting a new project - building the future of their company - on Node.

I mean it makes sense from a hiring point of view because JS developers are everywhere, but it doesn't make sense from a business point of view, or right-tool-for-the-job.

But maybe that's me being judgmental. I mean PHP is fine for back-end too, if that's what they were replacing.
