I cannot seem to find window.navigator.sendBeacon. In JS I usually just do navigator.sendBeacon. Does anyone in here have any knowledge to share?

Seems like it's not defined in Kotlin, use dynamic:
window.navigator.asDynamic().sendBeacon(...)

OK, thanks. Do all browsers implement this now? I have a check first: if(navigator.sendBeacon) { ... }, but I guess I can simply js("") the whole thing.

Better off developing a mapping file for the missing parts of the JS API not covered by Kotlin JS, which are going to be used in the program.

[hallvard]

Maybe. But for small projects, a one-time js("") is better, I think.

Going the asDynamic() route for small projects is easier though (don't need to deal with the JS syntax checks that occur with the js function).
