Web/DevBeginner
The programming language of the browser that makes pages interactive — clicks, forms, popups, and live updates.
In plain English
The programming language that makes web pages interactive, and with Node.js it also runs on servers.
Analogy
Like the muscles that make the body actually move.
Why it matters
It powers every interactive behavior, so it's the language behind custom funnel logic, embeds, and automations in the browser.
In practice
