I watched a talk by Douglas Crockford on the good parts in Javascript and my eyes were opened. At one point he said, something like, "Javascript is the only language where good programmers believe they can use it effectively, without learning it." Then I realized, I am that guy.

In OO Javascript constructor pattern: neo-classical vs prototypal, I learned that constructors using prototypal inheritance can be 10x faster (or more) than constructors using the so-called neo-classical pattern with closures as proposed by Crockford in his "Good Parts" book and presentations.
