What DOMinates the Web?
What is the DOM?
The DOM stands for Document Object Model. It is an object-oriented representation of objects and nodes that make up the content for the documents that are seen by its users on the web. The documents themselves are in HTML and XML format and each web page that you visit is considered a document. Whereas the nodes of each document are assembled in a tree structure.
Here is an example of a single DOM from Wikipedia:
The purpose of the DOM is to allow the manipulation of the documents with programs and languages that can change the structure, style and content in the browser. It is built up of multiple APIs and available in most web browsers we use today. Different browsers will have different DOMs available to them which can affect cross-browser functionality when building applications. Some of the different types of objects that are employed are
Without the DOM, programming languages wouldn’t have any reference to the model of web pages or documents and their content. Since the DOM is not a programming language itself and also works separately from any language, it is able to be manipulated by any scripting language without much hassle or specific installation.
Understanding and being able to properly control the elements of a web page will aid programmers in their pursuit of building more efficient applications for the web.
