Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1JSX is a syntax
that looks like HTML inside JavaScript.
- 2The compiler turns it
into React element creation calls.
- 3It lets you mix

- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.
EXAMPLE — See it in action
Here's a short line you can speak, broken into clear beats:
Note: Adapt this scaffold to your own project — keep it under 60–90 seconds.
Key takeaway
JSX is a syntax that looks like HTML inside JavaScript. The compiler turns it into React element creation calls.
