When working with the DOM, it is important to understand the difference between a node and an element.
A node refers to any object in the DOM, including:
- Elements like
<div> or <h1>.
- Text nodes, which represent the content inside elements.
- Comments, representing HTML comments (
<!-- -->).
- Other node types, such as document fragments and attributes.
An element is a specific type of node that represents HTML elements, such as <div>, <p>, or <ul>. Elements are a subset of nodes, meaning all elements are nodes, but not all nodes are elements.
ThechildNodesproperty returns all nodes inside .container, including text, elements, and comments, whereas the childrenproperty returns only the HTML elements, ignoring text and comments.
