The JavaScript DOM (Document Object Model) is a programming interface for web documents. Programs can use it to change the structure, style, and content of a document. JavaScript is used to interact with the DOM and manipulate web page elements.
When a web page is loaded in a browser, the browser creates a Document Object Model of the page, which is essentially a hierarchical tree-like representation of the HTML elements on the page. Each element on the page is represented as an object in the DOM tree, and JavaScript can access and manipulate these objects to modify the page.
JavaScript provides a number of methods and properties to interact with the DOM. As an example, you can use JavaScript to:
Select and modify HTML elements and attributes on a page.
Create/add new HTML elements, Attributes and add them to the page.
Remove HTML elements, Attributes from the page.
The content and style of HTML elements can be changed.
User events such as mouse clicks and keyboard input are handled.
In summary, the JavaScript DOM allows developers to create dynamic and interactive web pages by manipulating the HTML elements and their properties in response to user interaction or other events.
