A modern programming language that makes developers happier.

kotlinlang

is equality for maps just checking the object reference, or is it seeing if they contain the same data

Structural equality: <https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/-abstract-map/equals.html>

Which is more formally defined here: <https://docs.oracle.com/javase/8/docs/api/java/util/Map.html#equals-java.lang.Object->

So in the end it's `equals` on the keys and values.

In Kotlin:
`==` always check for structural equality calling `.equals()` method under the hood
`===` always checks for referential equality

This is  more unified approach, then in Java

But of course you still need to look at what `.equals()` does!

Yeah works, the issue I was having was unrelated. Just worked since the key type was string and the value was a data class
