What is Component?

A reusable building block of a user interface that can be combined to create complex pages

Why It Matters

Components make code more organised, reusable, and easier to maintain

Real-World Example

A 'Button' component used throughout your app ensures all buttons look and behave consistently

“Understanding terms like Component 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
