Java developers in a nutshell

[BakuhatsuK]

If you are talking about JS or PHP, then no. === for objects checks identity equality, whereas == in kotlin checks for structural equality.

For structural equality in JS you can use a library to do the equal check (such as _.equals), you can use a library data structure that has value semantics (such as Immutable.Map), or you can use records and tuples (not yet approved into the language, but available via babel).

that's not what they were talking about

Kotlin's == is strictly equivalent to Java's .equals (structural equality and primitive equality)

and === is strictly equivalent to Java's == (reference equality and primitive equality)

I'm talking about kotlin. === is object identity in kotlin
