Classification of objects
Built-in Object provides a common function for expressing web pages. As soon as the web page is loaded by the browser, it can be used immediately without any action.
- Standard Built-in Objects (or Global Objects)
- BOM (Browser Object Model)
- DOM (Document Object Model)
Except for Standard Built-in Objects, BOM and DOM are classified as Native Objects. In addition, user-generated objects are called Host Objects.
Host Object
User-generated objects. Built-in Object and Native Object are constructed after the constructor or object literal is defined and extended by the user.
