Number Of Nodes Returned In Mutationrecord.addednodes Nodelist (mutationobserver)

MutationRecord.addedNodes returns NodeList with nodes detected as added in my document. When I use obj.appendChild() method, mutationObserver detects it and returns this ONE node i

Solution 1:

Judging by the spec one appendChild corresponds to a single-node addedNodes array.

addedNodes usually contains many nodes during the initial page load and, naturally, if many nodes were inserted by js code in one operation via insertAdjacentHTML, or document.write, or .innerHTML, or .outerHTML, or DocumentFragment with many nodes.
