Concept

JavaScript

JavaScript is a programming language that adds interactivity to web pages. It runs in web browsers, allowing developers to create dynamic content, animations, and complex user interfaces.

You can now explain JavaScript — what it is, how it works, and why it matters.

Why it matters

It is essential for modern web development, enabling rich and responsive user experiences. Developers and founders use it to build interactive websites and web applications.

How it works

JavaScript code is embedded within HTML and executed by the user's web browser. This allows for changes to be made to the webpage in real-time without needing to reload the entire page.

What's happening now

JavaScript powers various projects, including those offering task progress UIs for web applications [1] and providing examples for AI agents to generate trade review charts [2].
