Treehouse TeacherYou could. But what about this scenario: What if you don't know how many items are supposed to go in the list?
Imagine for a second you have a website (similar to Trello) where users can make a ToDo list. And each item they add is formatted as a <li> item. You have absolutely no way to know how many items they may want to add. Instead you could have JavaScript add each item to an array and then build up a list from that array. This makes your code and website much more flexible

8,614 PointsWith Javascript you can dynamically add HTML-Elements to your website. If you use only HTML, then this HTML is shown fixed on your site.
You can for example tell Javascript to show HTML-Elements on the website if a user presses a button and hide the same HTML-Elements when an other click with the mouse is made. Using these Javascript methods on your website is made easier by using a Javascript framework like jQuery.
