JavaScript DOM (Document Object Model) is a programming interface that allows developers to interact with and manipulate HTML and XML documents. The DOM represents an HTML or XML document as a tree-like structure, with each element in the document represented by a node in the tree.
Through the DOM, developers can access and modify the content, structure, and style of an HTML or XML document. They can add, delete, or modify nodes and their attributes, change the text content of elements, and apply CSS styles to elements.
The DOM API provides a set of methods and properties for accessing and manipulating document elements, including getElementById, getElementsByTagName, and querySelector. It also provides event handling capabilities, allowing developers to create interactive web applications that respond to user actions.
JavaScript DOM is an essential part of modern web development, and is used extensively in creating dynamic and responsive web pages and applications.
