After learning about HTML and CSS, we are ready to learn about the final piece of front-end web programming, and that is JavaScript. This client-side programming technology allows us to add functionality to our HTML pages. It will enable us to interact with our HTML pages more dynamically. It may look a little intimidating at first, but remember you have seen these concepts before. You saw them in Scratch, Alice, and Code.org. We are just writing them down now instead of dragging and dropping code before something shows up on the screen. Also, you are making the computer do something that you tell it to do. That’s cool! Let’s continue to see what JavaScript can do for us.
