Is there a way to add an entire array of child nodes to a parent node in a single operation using JavaScript?

Question

Is there a way to add an entire array of child nodes to a parent node in a single operation using JavaScript?

Is there a quick way in JavaScript to attach an array of child nodes to a parent node all at once?

I'm looking for a method that will avoid triggering unnecessary repaints.

So far, I attempted using parent.appendChild(arrayOfNodes), but it resulted in an exception.

Currently working on a reusable component for multiple projects, and hoping to steer clear of dependencies on libraries such as jQuery or Zepto.

One efficient way to append multiple nodes to an existing element is by utilizing an intermediary DocumentFragment. This method may seem a bit complex, but it tends to outperform adding nodes one by one:

var tempFrag = document.createDocumentFragment();
for (var j = 0; j < elementsArray.length; ++j) {
    tempFrag.appendChild(elementsArray[j]);
}
targetElement.appendChild(tempFrag);

Although this solution may be considered outdated, I encountered a similar issue and devised a straightforward approach. My method entails creating a basic function that accepts a parent node and an array of child nodes without modifying any prototypes or introducing unnecessary complexities...

 function attachKids(parentNode, childNodes) {
     for (var j=0; j<childNodes.length;j++) {
         kid = childNodes[j];
         parentNode.appendChild(kid);
     }
     return parentNode;
 }

Incorporating a new function into the Node element, you have the option to create a method that internally triggers the appendChild method:

(function () {
  Node.prototype.addMultipleChildren(arrayOfNodes) {
    var total = arrayOfNodes.length;
    for (var index = 0; index < total; index++) {
      this.appendChild(arrayOfNodes[index]);
    }
  }());

This method can be utilized in the following manner:

node.addMultipleChildren(arrayOfNodes)
