Can someone help me understand why MutableMaps in Kotlin JS don't have all the methods I expect they'd have? E.g. put().

[trevjones]

map.put //this is a property get
map.put(key, value) //put fun call
map[key] = value // sugar for put

[Janelle Fullen]

There isn't a put function defined on the map object returned by Kotlin. This evaluation is being done in a Javascript console.

[Zachary Grafton]

Is the method name mangled? AFAIK overloaded methods get name mangled when compiled to Javascript.

[Janelle Fullen]

No, I don't see any mangled method for put, or many of the other API specified methods

[Janelle Fullen]

I think that MutableMap is an interface..which is why these aren't defined
