jotai breaks ie11 on nextjs with arrow function

Hi, I am testing this great lib and found out it breaks ie11 on next js with the arrow function.

ie 11 reports this error:

SCRIPT1002: Syntax error

_app.js (11916,31)

And it points to this line of code:

const hasInitialValue = atom => 'init' in atom;

I understand jotai supports ie11. It seems its standard dist output doesn’t transpire arrow function.

Any idea how to transpire it to work with nextjs on ie11? Sorry if it is a naive issue. Couldn’t find an issue addressing this.

busy recently. Would twist nextjs config later. thanks anyway.

Using https://github.com/martpie/next-transpile-modules I got it to run in IE11.

// next.config.js
const withTM = require('next-transpile-modules')(['jotai']);
module.exports = withTM();

Thanks for confirming. I guess this is a recommended solution at the moment.
