For example I have two DOMNodes: let node1 = document.querySelector('#node-1'); let node2 = document.querySelector('#node-2');

How do I bine them into a NodeList object? Is there an easy solution like array.push(item)?

You can add both nodes into a document fragment:

var docFragment = document.createDocumentFragment();
docFragment.appendChild(node1);
docFragment.appendChild(node2);

And if you really want them in a NodeList do:

var list = docFragment.querySelectorAll('*');

The down side to this is that as soon as you append the nodes to the document fragment you remove them from the actual document.

Consider this as an addition to Orr Siloni's answer:

If we don't want the node to be removed from the DOM, we can append a copy of the node using node.cloneNode().

var nList = document.querySelectorAll('[id^="node"]');

Collect all nodes with an id that starts with "node".

var nList = document.querySelectorAll('[id^="node"]');
for (var i = 0; i < nList.length; i++) {
  var node = nList[i].id;
  console.log('Node: ' + node);
}

<div id="node-1">node-1</div>
<div id="node-2">node-2</div>
<div id="notnode-3">notnode-3</div>
<div id="check">Check the console (F12, then choose the 'console' tab)</div>
