JavaScript (JS) is a programming language web developers use to create dynamic interactions and effects for webpages and applications.
Developers typically use JavaScript alongside HTML and CSS, markup languages that structure and style web content, respectively. Markups define and present text, but lack the dynamism to create interactive content. JavaScript, on the other hand, facilitates element-building to improve user experiences by allowing you to create animated graphics, dynamic background colors, and dropdown menus.
