Another pitfall to avoid is trying to inspect a large number of nodes at once. It is much better to narrow down the search to a specific subset of nodes and then use built-in methods to find the desired nodes. For example, if we know that the node we are looking for can be found inside a specific div element, then we could use the following code example:
function myJS(){ let subsetElements = document.getElementById("specific-div").getElementsByTagName("*"); for(let i = 0; i < subsetElements.length; i++) { if(subsetElements[i].hasAttribute("someattribute")) { // Do something with the node that was found... break; } }}
Thus, this search will be much more efficient and return results much faster than if we ...
