Dom is the simulation of HTML pages into an object, if JavaScript is only performing some calculations, loops and other operations, and can not manipulate the HTML will lose its meaning. Dom is the model of an HTML page that makes each label an object, and JavaScript can programmatically control the text boxes, layers, and so on in the Web page by invoking the properties and methods in the DOM. DOM Javascript is the main component of making interactive web. Using DOM, Javascript can communicate with HTML elements via the API. There are still many DOM Javascript events and methods that I did not discuss on this occasion, but among the many events and methods in the DOM API javascript, the list above is the one that is used most often. The Document Object Model (DOM) connects web pages to scripts or programming languages by representing the structure of a document—such as the HTML representing a web page—in memory. Usually it refers to JavaScript, even though modeling HTML, SVG, or XML documents as objects are not part of the core JavaScript language. In this video tutorial of JavaScript fundamentals, we will study and understand the concept of Document Object Model also known as DOM.Document Object Model( Yo Ninjas, in this JavaScript tutorial for beginners, I'll be walking you through what the DOM is and how we use it to interact with our web pages.The DOM st JavaScript (/ ˈ dʒ ɑː v ə ˌ s k r ɪ p t /), often abbreviated as JS, is a programming language that conforms to the ECMAScript specification.

What is DOM? DOM is a data representation of the objects in the HTML and XML pages. The document loaded in your browser is represented by a document object model. Moreover, it is a “tree structure” representation created by the browser that enables the HTML structure to be easily accessed by programming languages. Additionally, the DOM represents the document as nodes and objects.
