Do you know whether Jet Pack Compose for Web is Internet Explorer compatible? When I try our app I get syntax error on line 19:
I'm not JS expert so I don't know what it means.
Is the solution somehow change target JS version for Kotlin compiler?

It isn’t compatible, not only because of JS target. It may need some polyfills.
@[JB] Shagen, can you take a look on JS target, why webpack uses ES6 while Kotlin/JS can’t use ES6 yet?

We don't support IE and even if we'll figure out what's going on with webpack (which looks like a misconfiguration on a kotlin tooling level rather than in compose) there still won't be any guarantees on a API compatibility level. Microsoft itself is dropping support for IE and we just don't have reasons strong enough to test against it

Still someone can try to use polyfills to run it on IE without our support.

"Microsoft itself is dropping support for IE" 👀 Gotta go read up on that. I guess they have a new browser?

They have EDGE

Yeah, I'm pretty sure EDGE was released back in 2015 🤣
so I'm not sure if it can be described as a "new" browser anymore 🤣. But yes, IE is being replaced and will be past end of life by the time Compose for Web goes stable.
