JavaScript Essentials is all about learning the basic parts of JavaScript, a popular language used to make websites interactive. It helps control things like buttons, animations, and pop-up messages on a webpage. When you see a webpage respond to your actions—like a menu dropping down when you click it—that’s JavaScript at work.
This essential training teaches you how JavaScript works, including how to write simple programs, use variables, respond to user actions, and more. It’s a great starting point for anyone who wants to build websites or learn programming. With these basics, you can begin creating dynamic websites that react to users in real time.
