Most server side code is Java, quickly followed by PHP. And of course next to JS, you have C#, Asp.Net, Ruby, Python, and Go. I'd say that given that: - a lot of people only know JS (like designers) - JS has a monopoly on the front end and is the only language that can be used on the front and back - JS has existed for as long as Java (C#, Ruby and Go are way younger) - there are JS materials everywhere given the web popularity - the web is the most popular plateform in the world The fact, as a freelancer going from company to company, I see so little JS on the server compared to other languages tells a lot.
