The childNodes property returns a collection of a node’s child nodes, as a NodeList object.
The nodes in the collection are sorted as they appear in the source code and can be accessed by index numbers. The index starts at 0.
Note: Whitespace inside elements is considered as text, and text is considered as nodes. Comments are also considered as nodes.
Tip: You can use the length property of the NodeList object to determine the number of child nodes, then you can loop through all child nodes and extract the info you want.
This property is read-only.
Tip: To return a collection of a node’s element nodes (excluding text and comment nodes), use the children property.
Tip: element.childNodes[0] will produce the same result as the firstChild property.
