JavaScript – HTML DOM Methods

HTML DOM methods are JavaScript functions that allow you to interact with and manipulate the elements of an HTML document (web page). These methods provide a way to perform various actions on HTML elements, such as retrieving elements, modifying their content or attributes, and responding to user interactions.

Within the DOM, every HTML element is represented as an object, and the programming interface consists of the properties and methods associated with each of these objects.

A property holds a value that can be changed. For example, you can use properties to modify the content inside an HTML element.

What is the method?

A method is an action that you can perform, such as adding or deleting an HTML element.
