range to minimize the number of user domain name resolution, reduce the amount of data downloaded by users, increase concurrency and so on. In fact, we just clean up the pipes to make the pipes bigger, or add more pipes, or just try to keep the water inside the pipe a little less, so that it can be smoother.

There are a large number of log articles discussing jQuery selectors and their performance impact. As you know, you can use ID, TagName, or ClassName to select elements. Depending on the selector, jQuery uses the local method of the browser, for example, using ID or label to select an element, alternatively, you must manually retrieve the elements from the DOM when using the class name selection (because the corresponding getElementsByClssName does not exist in IE ). Analyze the two seconds in m

the following algorithm: The overall time complexity of this algorithm is O (N3). If it is calculated separately, the complexity is O (N x O x P ). However, when analyzing this code, we may find some strange scenarios: In the development environment, test data shows that the time complexity of the left branch (N-> M-> Heavy operation) is greater than that of the O and P on the right, so we only saw the left branch in our analyzer. In the production environment, your maintenance team may f
