Is JavaScript the Most Common Language in the World?
Richard Kenneth Eng

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.

Sure, you’re going to find examples here and there such as PayPal (though, frankly, comparing PayPal to financial institutions like RBC, Goldman Sachs, Bloomberg, etc. is pretty laughable). This isn’t a mathematical proof where finding a single counterexample disproves everything. I’m talking preponderance of evidence here. And most Fortune 500 shops aren’t basing their businesses on JavaScript code, and never will.

The StackOverflow survey basically says that JavaScript is super-popular with web development. Quelle surprise! But web development is nowhere near the entirety of the IT universe. Businesses that do more than just present a web interface to the public, and that’s nearly all of them, have to process their hard data in a safe, reliable manner, and few will trust JavaScript to the task.

I like Ted Doig’s closing remark about who is using JavaScript: “Those that matter don’t use it, and those that use it don’t matter.”
