I wouldn't go that far: when the optimization won't bring significant, measurable benefits, I prefer clear code over optimized code: code that is slightly slower or more memory-intensive but a lot more transparent and easy to maintain will win over the long term. The most important places to optimize are code inside a tight loop (say, the main loop of an interactive game) and code used for common data types (say, element, attribute and text nodes in a DOM). Optimizing code that will be called or instantiated thousands or millions of times is a good, easy hit; optimizing code that will be called or instantiated once or a dozen times is counterproductive. All the best, David
