I've spent most of the last 20 years working with JavaScript, and as ridiculous as it sounds, I never quite got the hang of it. Meanwhile other languages clicked within a few days.
I had a similar experience with e.g. Flash vs GIMP. Even after a decade of not using it, I found that the Flash shortcuts were intuitive to me, but GIMP (which I use every day, several times per day) never quite "clicks".
I'm not exactly sure why this is the case. Another example is that I rarely use Python, and yet find myself vastly more productive in it.
