Most in-demand programming language/framework for Fiverr that can be learned relatively quickly?

[danotto2]

Hi Fiverr! I’m a young guy who’s a computer science major and wants to break into freelancing. I know that there are some articles describing in-demand skills on Fiverr, but I’d like to know from you. Is there a language/framework that’s somewhat quick to learn and that’s in high demand? I want to get started soon. I have some certificates from SoloLearn but they only cover basic concepts and I’ve only taken one valid programming course at university so far. Any suggestions?
