As you'll note below, this method has been modified to walk // the linked list of child nodes rather than access the child by index // directly, even though there are two (2) APIs in the DOM that do this for us. // If you're thinking to yourself, "What an oversight! What an opportunity to // optimize this code!" then to you I say: stop! For I have a tale to tell. // // First, this code must be compatible with simple-dom for rendering on the // server where there is no real DOM. Previously, we accessed a child node // directly via `element.childNodes[index]`. While we *could* in theory do a // full-fidelity simulation of a live `childNodes` array, this is slow, // complicated and error-prone. // // "No problem," we thought, "we'll just use the similar // `childNodes.item(index)` API." Then, we could just implement our own `item` // method in simple-dom and walk the child node linked list there, allowing // us to retain the performance advantages of the (surely optimized) `item()` // API in the browser. // // Unfortunately, an enterprising soul named Samy Alzahrani discovered that in // IE8, accessing an item out-of-bounds via `item()` causes an exception where // other browsers return null. This necessitated a... check of // `childNodes.length`, bringing us back around to having to support a // full-fidelity `childNodes` array! // // Worst of all, Kris Selden investigated how browsers are actualy implemented // and discovered that they're all linked lists under the hood anyway. Accessing // `childNodes` requires them to allocate a new live collection backed by that // linked list, which is itself a rather expensive operation. Our assumed // optimization had backfired! That is the danger of magical thinking about // the performance of native implementations. // // And this, my friends, is why the following implementation just walks the // linked list, as surprised as that may make you. Please ensure you understand // the above before changing this and submitting a PR. // // Tom Dale, January 18th, 2015, Portland OR prototype.childAtIndex = function (element, index) { var node = element.firstChild;
