| Video Discription | The lecture goes over more JavaScript. You learn how to play a sound when you click a button. You learn to make a prototype image gallery with a button that when click shows the next image. Along the way you learn about JavaScript arrays, which are lists of things. Those things are called elements. You can access array elements using the square bracket notation. You need to provide the index or position of the element in the array, counting from zero. So the first element would be accessible at index 0. Not one. The number of elements in array is called its length. The lecture goes over how to make a comment form so users can leave a message that is added to the message list in the page. This functionality is very similar to when you post a comment on the social media platforms such as Twitter or X, Facebook, Instagram, etc. The lecture also teaches you how to debug JavaScript code in the browser with the Developer Tools (DevTools). You learn how to set up breakpoints and walk through the code, investigating the variables and getting to know the various objects used, such as the event object. You also get to learn how to fabricate HTML elements in memory, manipulate them, and finally inject them into the document object model (DOM).
