What is DOM? What is Shadow DOM? Interview question

Shadow DOM addresses the DOM tree encapsulation problem

What is DOM?

DOM is Document Object Model

It is a representation of an HTML document

It is used by browsers to determine what to render on the page

What is Shadow DOM?

Shadow DOM is a “DOM within a DOM”

Core idea is to encapsulate DOM from the rest of the page

So styles and javascript can be specific to a widget and not to whole page

With Shadow DOM, elements can get a new kind of node associated with them

This new kind of node is called a shadow root

An element that has a shadow root associated with it is called a shadow host
