📦 @babel/plugin-proposal-private-property-in-object

Enables the use of the in operator to check for the presence of private properties on JavaScript objects. This Babel plugin transforms modern code using private fields with the #private in object syntax to be compatible with older environments that don't natively support this feature. It ensures that your code doesn't break when running in older browsers or Node.js versions by providing a polyfill. Simplifies writing cleaner, more modern JavaScript with private class fields.
