If my goal is to learn python and javascript as well as possible over the next 18 months...should I learn them both from the ground up at the same time? should I get the hang of python first? Any insight? Pretty new to this. Just finished HeadFrist Python and Automate the Boring Stuff, and am starting to get the hang of making small programs with python, trying to escalate into bigger and more complex problems now. Is there a right time to start learning Javascript? or should I wait?
