Not only does it automate processes that users would, in an HTML-only site, need to perform manually, but it also empowers a website to react to a visitor’s input. With JavaScript, a website becomes dynamic.

With only HTML and CSS, a web page is unchanging and relatively simplistic.

CSS, on the other hand, centers more on formatting and appearance it allows developers to describe how the HTML should look to a visitor. Most common actions, such as transactions, submitting customer feedback, and even logging in, are facilitated by HTML code. In simple terms, this means that developers use JavaScript to build the part of a website that ordinary visitors can see and interact with, also known as the “front end.” While the programming language can technically be used to create complex programs, its primary application lies in web development.įront end programmers typically use JavaScript in conjunction with two markup languages, HTML and CSS, to create all of the elements that a user can see and interact with directly. JavaScript is typically used as a client-side scripting language for front end development.
