Paul Irish commented on Speed Up Your JavaScript Gotcha. It’s certainly hard to estimate how many scope chain hops you have in your entire application. :) Thanks for the detail. 6 months ago
Paul Irish commented on Speed Up Your JavaScript I’ve often wondered about scope chain traversing. It’s mentioned in a number of javascript optimization recommendations, but I hadn’t seen any data on it until here (slides 17-18). So if this data is over 200,000 iterations, and the worst delta is 20ms for 1 chain traverse, then we’re looking at ~0.0001ms per. Right? And really only IE that has a measurable difference. I guess I’m not convinced yet that this has much impact. :/ 6 months ago
