JavaScript is a programming language and platform that allows users to use a wide range of functions and commands that other platforms do not provide. For example, JavaScript allows websites to run interactive menus, flash-based video games, and high quality interactive videos. However, although JavaScript may be used on a website, the viewer’s browser may not have JavaScript enabled, which may prevent the viewer from seeing and using the components that the website has to offer.

Applications

As mentioned before, JavaScript can be used to provide websites with additional features that HTML and CSS do not, such as interactive menus and videos. Likewise, JavaScript can be used to provide interactivity to logos and other image based content.
