jQuery is a very powerful tool which provides a variety of DOM traversal methods to help us select elements in a document randomly as well as in sequential method. Most of the DOM Traversal Methods do not modify the jQuery object and they are used to filter out elements from a document bas...
it doesn't include the features you don't need, e.g. Array iteration functions (forEach,map,reduce, etc.) or Ajax. There are perfectly good polyfills outthere. Good documentation Permissive BSD-like license the author knows Javascript and the DOM (or I think so ;-) ). ...

That means it does not have a .reduce() method or a .map() method. Replacing the array .reduce() is fairly easy. We can just borrow the Array.prototype version and the JS engine will figure it out for us. But we have to tweak our hasChildren() function a little bit first: ...
HashMap的尾部遍历问题 (Tail Traversing) JDK1.7的HashMap在实现resize()时,新table[]的列表采用LIFO方式,即队头插入。 这样做的目的是:避免尾部遍历。 避免尾部遍历是为了避免在新列表插入数据时,遍历到队尾的位置。因为,直接插入的效率更高。 对resize()的设计来说,本来就是要创建一个新的table,列表的顺序不...
