Why is JSX used in React?
JSX makes it so we can pass around tree structures composed of HTML or React elements as if they were standard JavaScript values.
Why is JSX good?
Not only do people find JSX to be helpful visual aids when working with JavaScript UI, utilizing JSX allows React to show more useful error messages and warnings for easier debugging.

Is JSX a programming language?
