A modern programming language that makes developers happier.

kotlinlang

There are some exceptions that there is no workaround, especially in Java library conversion usage in kotlins, but mostly yes

<@URN6NJNBS> is correct - when you are interacting with Java libraries there are points where you _must_ behave like Java.  I've found that JPA/Hibernate entities are much easier to write using `lateinit var`  because that is how the underlying mechanics of the framework operate.

Within kotlin I would not use `lateinit`  as there is always a more kotlin-ish way to write your code.

I use it in tests for reflection based runners (like Spring's) with annotations like `@MockBean`

Usually I try to avoid it, but it is there if you really need it.

Tangent: !! In production code is what drives me crazy :zany_face:

There are no rules when writing tests :slightly_smiling_face:
