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 had searched for it within a large number of nodes.
