>old canard about caching the length of an array when iterating over it I think there are still places where you need to do this (please correct me if wrong, or mention some other cases): - when iterating over DOM nodelists in JS (why doesn't the browser cache this as well?) - if using strlen in C/C++ (for the latter, you should use string.length() instead).
