Why is JavaScript useful for front end developers?

Answer 1

Hi, Shane!

Front-end development comprises a web page's or web application's structure or "skeleton" (HTML), styling or "looks" (CSS), and interactivity (JavaScript).

So JavaScript is useful for front-end developers to add interactivity to the web pages or web applications. Submitting a message through a contact form or clicking a button that executes certain behavior are some examples of the interactivity you can achieve with JavaScript.
