FAQs

Which format should I choose?

babel.config.json suits most projects. Use babel.config.js when you need logic or comments in the config, and .babelrc for file-relative configuration.

What does @babel/preset-env do?

It compiles modern JavaScript down to a version your target browsers support, based on your browserslist query.

Do I need the plugins?

Only tick a plugin when your code needs it — for example, class properties for the class fields syntax.

Is my data sent anywhere?

No. The config is generated entirely in your browser and never transmits or saves your entries.
