Lecture 156:- DOM

The Document Object Model (DOM) is an API for representing and manipulating web page content as objects. The DOM represents an HTML or XML document as a tree structure, with nodes representing elements, attributes, and text.

With the DOM, you can programmatically access and manipulate the structure and content of an HTML or XML document. This allows you to create dynamic and interactive web pages. You can use JavaScript to modify the DOM in response to user interactions or other events, such as page load or form submission.

The DOM provides a set of standard methods and properties for manipulating document content, such as adding and removing elements, changing element attributes, and modifying the text content of elements. You can also use the DOM to traverse the document tree, access parent and child nodes, and query the document for specific elements or attributes.

Overall, the DOM is a powerful and flexible tool for creating rich and interactive web pages. It forms the foundation of many modern web frameworks and libraries, and is an essential part of any web developer's toolkit.
