A modern programming language that makes developers happier.

kotlinlang

And what about <https://material-ui.com/> ?

there are wrappers developed by the community
check these two repos :
<https://gitlab.com/AnimusDesign/KotlinReactMaterialUI>
<https://github.com/cfnz/muirwik>

We had to rip out most of it to get decent performance on our app

I remember even some or their examples taking 10 seconds to first render

<@U1JP5M6LU> do you remember where was the problem exactly 
Because we use some of the components in one of our projects and there is no issues
Maybe if you can be more specific with which components cause this performance issues so we can check and avoid using them in our project

Thank you, I used murwik in the past, I will check the other one

Its a bit hazy and we didnt get completely to the bottom of it but as far as I can remember every single component we used from the lib had a massive overhead (maybe 20-40 ms. just to react render) compared to just a simple div.
