What JavaScript does
What JavaScript does
JavaScript is a programming language that lets a page react to data, time, and user actions. It runs as instructions: values are created, decisions are made, and visible results are updated.
Learning objectives
- Describe JavaScript's role in a web page
- Run a short program in a browser console
See how JavaScript adds behavior to an otherwise static page. Focus on explaining each decision in your own words before relying on a pattern or shortcut.
Example
const greeting = "Hello, QEVANTI";
console.log(greeting);Summary
KEY TAKEAWAYS
- JavaScript adds behavior and logic.
- The console is a useful place to test small ideas.
