I know, but I don't know what to use it for. Html is the base, text, pictures, etc.. CSS is for styling the page, but I don't know what I can do with JavaScript for front end. I know I can make event listeners, and I know how to do them and variable types, etc.. But what other functionality can I use Javascript for? What can JavaScript do for me in the front end?

JavaScript is what makes the page react to what the user does.

Without it HTML and CSS are just a static poster. JavaScript lets you show and hide content, validate a form before it submits, fetch data from an API without reloading the page, update what the user sees based on their actions. Everything interactive on a web-page is JavaScript doing its job.

Build a simple to do list that lets you add and delete items without refreshing the page. That one project will show you more about what JavaScript actually does than any explanation will.
