What is Client-Side?

Code or processing that happens in the user's browser

Why It Matters

Client-side code enables interactivity without needing to contact the server for every action

Real-World Example

Form validation that checks your email format before sending data to the server

“Understanding terms like Client-Side 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
