The Document Object Model ( DOM) is a cross-platform and language-independent interface that treats an HTML or XML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects.
JavaScript. JavaScript ( / ˈdʒɑːvəskrɪpt / ), often abbreviated as JS, is a programming language and core technology of the Web, alongside HTML and CSS. 99% of websites use JavaScript on the client side for webpage behavior.

Object is a categorization into which many programming concepts fall. For example, an object can be a programming language variable, data structure, function, or method. In object-oriented programming (OOP), an ...
In object oriented programming, the factory method pattern is a design pattern that uses factory methods to deal with the problem of creating objects without having to specify their exact class. Rather than by calling a constructor, this is done by calling a factory method to create an object. Factory methods can either be specified in an ...
Standards. ECMAScript ( / ˈɛkməskrɪpt /; ES) [ 1] is a standard for scripting languages, including JavaScript, JScript, and ActionScript. It is best known as a JavaScript standard intended to ensure the interoperability of web pages across different web browsers. [ 2] It is standardized by Ecma International in the document ECMA-262 .
v. t. e. The Browser Object Model ( BOM) is a browser-specific convention referring to all the objects exposed by the web browser. [1] Unlike the Document Object Model, there is no standard for implementation and no strict definition, so browser vendors are free to implement the BOM in any way they wish. [2]
