Doesn't work on IE-10 and IE-11

[collegeimprovements]

Would it be possible to support IE-10 and IE-11 by generating target files(via tsconfig) for IE-10,11 as well as modern browsers?

Currently it gives syntax error in Internet Explorer.

The errors would be interesting, but probably just missing polyfills since we compile via babel-env without browser config.

Looking through the code there doesn't seem to be anything special. It's using Set, Object.keys, Object.is.

It's probably the former (Obj.id). If you add a core-js polyfill, it will surely work. Could you import zustand/cjs and try adding corejs?

It indeed worked. Thanks a lot :)

Not sure if I should open up another issue, so I thought I'd ping here first: is there a reason that he ES Module source isn't transpiled for IE11 as well? If I am importing this with ES Module syntax with webpack for a web target, it's going to pick up the module entry point in package.json which includes stuff like Object.assign (a non-ES Module ES6) and not transpile it. I'd then have to transpile zustand myself. Is this intended?

Some reasoning/context: webpack/webpack#1979 (comment)

EDIT: Actually, looking at the build, it doesn't seem like Object.assign or Object.is are being transpiled anywhere even though

Sorry, I was confusing transformations with polyfills. However, it might help in the README to make list of polyfills that might be necessary if targeting IE11 (as that seems to have explicit support)
