On this first day of coding tutorials, we will start out with some jQuery. In order to set up a jQuery project, you need to download the library. Then, in your App.js, write $(document).ready(function(){}); This is saying that when the html page loads, run this code. In order to understand jQuery, you must be familiar with the jQuery object. A jQuery object is normally a DOM node. It looks something like this: $("div"); This code finds all the divs in the HTML page. Event listeners next week.
