What is JavaScript?

The programming language that makes websites interactive and dynamic

Why It Matters

JavaScript runs in every web browser and is essential for any interactive web application

Real-World Example

The dropdown menus, form validation, and animations on a website are typically powered by JavaScript

“Understanding terms like JavaScript matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”

Callum Holt, Founder, 13Labs
