What is Lazy Loading?

Delaying the loading of content or code until it is actually needed.

Why It Matters

Lazy loading speeds up initial page load by only downloading what the user can see right now.

Real-World Example

Images below the fold only load as the user scrolls down to them, not when the page first loads.

“Understanding terms like Lazy Loading 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

From definition to deployment

Knowing the term is step one. Using it in something real is the rest.
