Learn DOM scripting with online courses
What is DOM scripting?
DOM is short for Document Object Model, a programming interface used to manipulate HTML and XML documents, such as a web page. It is an API to help developers access and modify DOM trees, which is the structure for a document’s contents. The tree of nodes is a building block of modern, interactive websites that lets you add, delete, or alter page content, styling, and user action responses via tags.
For example, users will be able to click a button to trigger an action, view a drop-down menu, increase or decrease window size, input text, or receive error messages. Programmers, web developers, and engineers can dynamically update content on web pages without having to reload the page or rewrite code, which creates smoother and faster response times.
Whether you use Angular, React, Vue, or any other framework to create your web application, the DOM is what you’ll use behind the scenes to create an interactive experience.Footnote 1
