It's deliberately misleading to say that jQuery and other libraries use a pattern where (internal to the library) there are constant, deep chain lookups. The entire "problem" can be easily "fixed" with the solution above--cache local references so you're not doing deep-lookups constantly (which, if you look at the source of the referenced libraries, you won't find). As I said; it's either deliberately misleading--or the author's understanding of javascript is too limited as to be making claims that "jQuery and other libraries could have been 98% faster." A comment, by the way, which was later modified to state "if you are not a JavaScript Ninja your framework code could have been up to 98% faster." Sorry, I don't file that knowledge under "Javascript Ninja" knowledge--and moreover, the original comment was designed to say, "My library is faster / better than all of these popular libraries." [Edit] To my (admittedly cynical at times) that adds up to deliberately misleading.
