Introduction to JavaScript

JavaScript is a scripting language for creating dynamic web page content. It creates elements for improving site visitors’ interaction with web pages, such as dropdown menus, animated graphics, and dynamic background colors.

Additionally, JavaScript streamlines processes that users would otherwise need to do themselves, such as reloading a web page to see its changes.

Developers generally use JavaScript alongside HTML and CSS to create a dynamic website. The scripting language works well with CSS in formatting HTML elements. However, it still maintains user interaction, something that CSS cannot do by itself.
