Dom Document Object

Document Object:
Each HTML document loaded into the browser will become a Document Object.
The document object allows us to access all elements in the HTML page from the script.
Tip: The document object is part of the window object and can be accessed through the document DOC ument attribute. , Document Object Description:

The htmldocument interface extends the DOM Document Interface and defines HTML-specific attributes and methods.

Many Attributes and methods are htmlcollection objects (in fact, read-only arrays that can be indexed with arrays or names), which store references to the anchor, forms, links, and other Scriptable elements.

These set attributes are derived from level 0 Dom. They have been replaced by document. getelementsbytagname (), but they are often used because they are convenient.

The write () method is worth noting that when a document is loaded and parsed, it allows a script to insert dynamically generated content into the document.

Note that in level 1 Dom, htmldocument defines a very useful method named getelementbyid. In Level 2 Dom, this method has been transferred to the document interface, which is now inherited by htmldocument rather than defined by it.
