I started with Golang not too long ago, and I loved the fact that I can create a web application with a couple of lines of code. But, as always frameworks help to take that web application to places. Being a practical person who develops apps for side projects and for a living, I cannot simply overstate this fact.

If you had enough of single threaded behaviour of Node and are ready for the next level (/s) - I strongly recommend you evaluate Go for your next project. Javascript is the most used language in the world and that status will not change in a hurry - thanks to its frontend nature.
