Needs Technical Review
RE: “This page has been flagged... Technical Review... inaccurate...”
Consider the wiki model, widely propagated by Wikipedia: shouldn't the inaccuracy warning (re: this page has been flagged...) appear at the top of the page (or section); before any content (i.e. as a label) to warn the reader that the content is in question as possibly inaccurate, requiring revision, or otherwise potentially incorrect. In the current state, 2011-01-14, it reads rather as an afterthought. --tweedle 2011-01-14
Section "Arrays" - suggestions for iterating
The two suggested alternatives not only make the code far more unreadable but also isn't based on any messurable benefits. I did a simple test (https://gist.github.com/1780215) for the common syntax and these two suggestions and found almost no improvement in performance.
Classic for loop
|For loop with length cached||473ms|
|For loop with short signature||468ms|
Considering that the last example can easily break your loop at least it should be removed. That is not the way to build robust applications.
