What is @babel/plugin-proposal-export-default-from?
The @babel/plugin-proposal-export-default-from package allows developers to use the proposed export default from syntax in their JavaScript code, which is not yet part of the ECMAScript standard. This plugin transforms the proposed syntax into a form that can be understood by current JavaScript engines.
Export default from syntax
This feature allows you to export a default export from another module in a single line. Without this plugin, you would need to import the default export and then export it, which is more verbose.
export v from 'mod';
