Could be, but it could also be that Node.js have much more libraries compared to Go, especially for databases, can escape typing if necessary using any, promise/async programming are much more easier with es6 (you can do a try catch without repeating etc)..array operations like map, reduce makes much easier to do quick and dirty functional programming etc. I can get much cleaner libraries for concurrent programming in Node.js lots of things you can do in Node.js takes roughly twice or more number of lines. Could be anecdotal, but say if I try another language such as Python I found it is more or less same as Node.js. Java is another language I can think that can slow you down. Of course the stricter typing, error handling etc can make for much more robust code in long run, but for someone who can afford to trade development time.
