Quick Reference
The collection item() method returns the element at a specified index in an HTMLCollection, which is an array-like list of HTML elements.
<p>This is the first paragraph.</p>
<!-- html element to place output -->
<p id="my_output"></p>// variables
let my_collection = document.getElementsByTagName('p');
let my_text = my_collection.item(0).innerHTML;
// output to HTML element
document.getElementById('my_output').innerHTML = my_text;Note
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.

HTMLCollection.item(index)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.
