I mean, I do know common pitfalls and I can use `this`, etc., it's just that I find it's easier to avoid them entirely and leads to more readable code IMHO. In a way my JS tends to just be very scheme-like.
Mine too! I've felt for many years that we were lucky that Eich happened to have read SICP not long before those fateful two weeks in 1995. For all that we all love to hate JS, the language of the web could have—and to judge by all historical precedents, should have—been much worse.
Crockford succeeded in popularizing JS, partly by stressing the Scheme-like features of the language, but I'm not convinced that's where the strengths of the language lay.
There ARE times where I had to optimize though (HTML5 game developer, and we target mobile so this is expected) but for the most part 'premature optimization is the root evil'.
