What are ARIA roles and why are they important?

Short answer: ARIA (Accessible Rich Internet Applications) roles make web content more accessible for users relying on assistive technologies (like screen readers).

Example code

<button role="switch" aria-checked="false">Dark Mode</button> role="switch" defines what the element represents. Follow me on LinkedIn: aria-checked communicates the state to assistive devices. Key Takeaway: ARIA makes dynamic interfaces accessible by adding semantic meaning beyond native HTML.

Real-world example (ShopNest)

ShopNest’s browser cart uses modern JavaScript: fetch APIs with async/await, modules, and clear error handling.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
