What is Polling?

Repeatedly checking for new data at regular intervals

Why It Matters

Polling is simpler than WebSockets and works when real-time isn't critical

Real-World Example

An email app checking for new messages every 30 seconds

“Understanding terms like Polling 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
