As StackOverflow mentions, and Dan Rowinski parrots: “Even Back-End developers are more likely to use it than any other language.”
Presumably, they’re referring to back-end programming using Node.js. Unfortunately, this is very misleading. As a friend of mine named Ted Doig, one of the finest engineers I know, told me: “For enterprise, JS may be used in the periphery, I grant you, but not where it really matters. ERP solutions like SAP aren’t using node.js, there’s no business case for it. So, yeah, while a company may have their website using JS, don’t expect any serious shop to be washing their critical Business Intelligence data through JS code. And any company that is fool enough to do so will be roadkill soon enough as they get steamrolled or acquired by smarter outfits.
