    JavaScript is event driven. You add event listeners to elements in the HTML and when those events are triggered on those elements then the corresponding code runs.

    JavaScript has four ways to communicate with the server.
    1. Using iframes (not recommended)
    2. Using xmlhhtprequest and listening for the response
    3. By adding additional script tags dynamically (to retrieve data only)
    4. By calling server generated transparent images (to send data only)

    JavaScript goes in a separate file attached to your HTML via a <script> tag immediately before the </body> tag

    Don't forget to start your JavaScript code with "use strict"; which makes it easier to find errors in your code.
