Why does JSX use className instead of class?

class is a reserved word in JavaScript, so React JSX uses className for CSS classes.

Why does JSX use htmlFor instead of for?

for is also reserved in JavaScript, so JSX uses htmlFor for label associations.

Can JSX use inline styles?

Yes, but JSX inline styles use JavaScript objects, such as style={{ fontSize: "16px" }}.

Do input and image tags need to be self-closing in JSX?

Yes. Void elements such as input, img, br, and hr should be self-closing in JSX.

Does this tool validate React code?

It helps convert HTML to JSX, but you should still review and test the output in your React project.

Is converted JSX executed by this tool?

No. The output is displayed as code only.

Can this convert SVG to JSX?

It converts common SVG attributes, but complex SVG markup may still need manual review.

Is my code uploaded to a server?

This browser-based BlinkCalc tool is designed to convert code locally and should not store user input.

Can I paste production code into this tool?

Avoid pasting private or proprietary code into any online tool unless you trust the environment.
