HTML Nodes vs Elements
In the HTML DOM (Document Object Model), an HTML document is a collection of nodes with (or without) child nodes.
Nodes are element nodes, text nodes, and comment nodes.
Whitespace between elements are also text nodes.
Elements are only element nodes.
childNodes vs children
childNodes returns child nodes (element nodes, text nodes, and comment nodes).
children returns child elements (not text and comment nodes).
Siblings vs Element Siblings
Siblings are "brothers" and "sisters".
Siblings are nodes with the same parent (in the same childNodes list).
Element Siblings are elements with the same parent (in the same children list).
