HTML DOM appendChild() Method in JAVA SCRIPT

Definition and Usage..
The appendChild() method appends a node as the last child of a node.
Tip: If you want to create a new paragraph, with text, remember to create the text as a Text node which you append to the paragraph, then append the paragraph to the document.
Tip: Use the insertBefore() method to insert a new child node before a specified, existing, child node.
Syntax: node.appendChild(node)
CODING:
<!DOCTYPE html>
<html>
<body>

<ul id="List1"><li>C</li></ul>
<ul id="List2"><li>C++</li><li>JAVA</li><li>PYTHON</li><li>HTML</li><li>CSS</li><li>JAVA SCRIPT</li><li>ERLANG</li><li>SQL</li><li>XML</li></ul>
