Quick Reference
The Element cloneNode() method creates a copy of a node (and all its attributes and their values), and returns the clone.
Note
A node can be an HTML element (div, span, p, h2, etc.), or it can be a text node (plain text, white space, a teb, a linebreak). Whereas, when referring just to an element, only the HTML elements are relevant.
<!-- source element -->
<ul id="my_list1"><li>Lamborghini</li><li>Ferrari</li></ul>
<!-- element to receive the clone -->
<ul id="my_list2"><li>Maserati</li><li>Alfa Romeo</li></ul>// variables
let my_node = document.getElementById("my_list1").lastChild;
let my_clone = my_node.cloneNode(true);
// output to the HTML element
document.getElementById("my_list2").appendChild(my_clone);Output
-Lamborghini
-Ferrari
-Maserati
-Alfa Romeo
-FerrariSyntax

JavaScript Notes:
- When using JavaScript, single or double quotation marks are acceptable and work identically to one another; choose whichever you prefer, and stay consistent
- JavaScript is a case-sensitive language; firstName is NOT the same as firstname
- Arrays count starting from zero NOT one; so item 1 is position [0], item 2 is position [1], and item 3 is position [2] … and so on
- JavaScript variables must begin with a letter, $, or _
- JavaScript variables are case sensitive (x is not the same as X)
We’d like to acknowledge that we learned a great deal of our coding from W3Schools and TutorialsPoint, borrowing heavily from their teaching process and excellent code examples. We highly recommend both sites to deepen your experience, and further your coding journey. We’re just hitting the basics here at 1SMARTchicken.
