Some DOM and DHTML basics~~
Your "Window" object represents a web browser window, which is also called a global object because all other BOM objects contained within it.
- Dynamic HTML (DHTML)
Normally containing examples of an application programming interface or otherwise known as API, allows us to structure objects with a set of properties and methods.
The hierarchy depends on a document's contents, where each item in the DOM tree is a node. Element, attribute, and text content nodes are generally the ones used.
