What makes a website interactive?

An interactive (or dynamic) website is a site with dynamic pages that can be modified by users. Most modern websites are interactive, while static websites (which have pages that appear the same for every user) were more prevalent until the early 2000s.

How does JavaScript make websites interactive?

<a href="https://www.codecademy.com/article/what-is-javascript">JavaScript</a> allows developers to add animations and other interactive elements to web pages and modify the data stored in a page’s DOM (Document Object Model). Creating dynamic websites was a lot of complex before Javascript was developed, and the internet largely consisted of static websites.

What kind of jobs use Javascript to build interactive websites?

Web Developers use JavaScript to build interactive websites. Specifically, Front-End Developers use JavaScript along with HTML and CSS to build the parts of the site you see in your browser, and Back-End Developers use JavaScript with frameworks like Node.js to manage the hidden processes in the background. Full-Stack Developers do both.

What else should I study if I want to build websites?

If you want to take your JavaScript skills even further and build better websites, learn how to use JavaScript libraries like Node, React, Vue, and Angular to streamline your development and expand your sites’ functionalities.
