How do I make this loop all children recursively?

Question

I have the following:

for (var i = 0; i < children.length; i++){
   if(hasClass(children[i], \"lbExclude\")){
       children[i].parentNode.removeChild(ch

You can use BFS to find all the elements.

function(element) {
    // [].slice.call() - HTMLCollection to Array
    var children = [].slice.call(element.children), found = 0;
    while (children.length > found) {
        children = children.concat([].slice.call(children[found].children));
        found++;
    }
    return children;
};

This function returns all the children's children of the element.
