The Document Object Model (DOM) is a programming interface for HTML and XML documents. It represents the structure of a document as a tree-like hierarchy, with each element of the document (such as a paragraph, image, or button) as a node in the tree.
The DOM allows developers to access and manipulate the contents of a document, such as adding, removing, or modifying elements, as well as changing the properties of elements, such as the text content, color, or style.
One of the critical features of DOM is that it allows the dynamic manipulation of web pages, this means that it allows developers to change the content, layout, or style of a web page after it has been loaded, this is the basis of the dynamic web pages we see today.
Overall, the DOM is a powerful tool for web developers, providing a way to access and manipulate the contents of a document, and create dynamic and interactive web pages. It’s a fundamental concept in web development as it allows developers to access, change, delete and add elements to the HTML structure of web pages, which makes it easier to build interactive web pages and web apps.
