JavaScript HTML DOM Node Lists

NodeList is a collection of document nodes returned by DOM methods like querySelectorAll() or childNodes. It looks like an array but is not a true array.

The NodeList object represents a collection of nodes returned by DOM methods like:

• document.querySelectorAll()
• element.childNodes

Unlike HTMLCollection, NodeList can contain any type of nodes: element nodes, text nodes, comments, etc.

You can loop through a NodeList using for, for...of, or forEach() if it's supported.
