That’s in case of forms, or
As far as I can work out,
I’m guessing that, in terms of speed, the difference, if any, will be next to nothing, since
What does throw me, is
To get back to my initial question, my guess would be: if I
want the most comprehensive object,
Could anyone clarify the distinction between the objects at hand? If there is a speed difference, however negligible, I’d like to know, too. If I’m seeing this all wrong, feel free to educate me.
To get all child nodes of an element, you can use the
By default, the nodes in the collection are sorted by their appearance in the source code. You can use a numerical index (start from 0) to access individual nodes.
Let us say you have the following HTML code:
The following example
selects all child nodes of the
Here is how the output looks like:
This is because whitespace inside elements is considered as text, and text is treated as nodes. It also applies to comments that are considered as nodes too.
If you want to exclude comment and text nodes, use the

What is a child node?
Any subnode of a given node is called a child node, and the given node, in turn, is the child's parent. Sibling nodes are nodes on the same hierarchical level under the same parent node. Nodes higher than a given node in the same lineage are ancestors and those below it are descendants.
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.
How do you get a child of node JS?
To get the first child element of a specified element, you use the firstChild property of the element:.
let firstChild = parentElement.firstChild; ... .
let content = document.getElementById('menu'); let firstChild = content.firstChild.nodeName; console.log(firstChild); ... .
The children() method returns all direct children of the selected element. The DOM tree: This method only traverse a single level down the DOM tree. To traverse down multiple levels (to return grandchildren or other descendants), use the find() method.
