Description: A text node is a type of node in the Document Object Model (DOM) that contains plain text. In the context of web programming, the DOM is a structured representation of HTML and XML documents, where each element, attribute, and text is turned into an object that can be manipulated using programming languages like JavaScript. Text nodes are fundamental because they allow the textual content of a web page to be accessible and manipulable. Each text node is associated with a container element, such as a paragraph or a heading, and can be created, modified, or deleted through DOM methods. For example, when adding or changing the text within an HTML element, one is directly interacting with text nodes. These nodes do not have attributes or children, which distinguishes them from other types of nodes in the DOM, such as element or attribute nodes. Manipulating text nodes is essential for creating dynamic web applications, where content can change in response to user actions or system events.
