Just out of curiosity — how are things like Longs implemented in Kotlin/JS if JavaScript only has floating-point numbers? :thinking_face:

They are implemented as objects iirc (whereas ints are implemented just as JS numbers)

Take a look at implementations:
• <https://github.com/JetBrains/kotlin/blob/432828a2dbfe85d3b08ce8d6c88e8b7a6b728ec7/libraries/stdlib/js-v1/src/js/long.js#L42|long.js>
• <https://github.com/JetBrains/kotlin/blob/8f37ace9ee6c1988fcb87095b79ac3b1dd0d8853/libraries/stdlib/js-ir/runtime/long.kt#L11|long.kt> 

Last one is used with new JS compiler backend
