I do not understand why we take the data from the form, assign it to variables and then append it to the div. this was done in a previous Javascript video with javascript. why is jquery needed for this?

Treehouse Moderator 145,858 PointsStuart is right on. jQuery is a JavaScript library that is designed to make JavaScript easier to use -- Much like Sass is for CSS.
There may be a function you want to add to a website that would comprise MANY lines of pure JavaScript code, but can easily be done in one or two lines of jQuery. Honestly, you'll see much more jQuery, especially when it comes to DOM manipulation, so if Front-end Development is your goal, then jQuery will be an essential knowledge base you will need.
