Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.

- 1JSX is HTML-like syntax
that compiles to React.createElement or the new jsx runtime.
- 2It must return one

className and event names are camelCase.
- 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.

Here's a short line you can speak, broken into clear beats:

Key takeaway
JSX is HTML-like syntax that compiles to React.createElement or the new jsx runtime. It must return one parent, which is why Fragments exist.
