Digital marketing term
JavaScript
JavaScript is the programming language that adds interactivity and dynamic behavior to web pages in the browser.
Detailed explanation
JavaScript (JS) powers client-side interactions: forms, menus, single-page apps, analytics events, and many third-party marketing tags. Together with HTML and CSS, it completes the core web triad.
