Please. The initial commits on Moon were in 2016, and I was playing around with a forked version of Vue locally in late 2015. I think it's extremely important to know what goes on under the hood of popular libraries.

And regarding the FreeCodeCamp profile--I made that account for my little brother (who was learning to program at the time). Along with that, I tried to help people out on the FCC Gitter[1] as much as I could, as teaching people is a good way to master something.
