Which is better and why?

:one: *This is broken*
```return binding.myField.getWidth() != 0 ? binding.myField.getWidth() : binding.otherField.getWidth()```
:two:
```return binding.myField.getWidth().let {
    if (it != 0) it else binding.otherField.getWidth()
}```
:three: by <@UAN39HN81>
```return if (binding.myField.getWidth() != 0) binding.myField.getWidth() else binding.otherField.getWidth()```

:two: because :one: does not compile. There is no ternary operator in Kotlin. I would go with :three: : `return if (binding.myField.getWidth() != 0) binding.myField.getWidth() else binding.otherField.getWidth()`

Another option is `return binding.myField.getWidth().takeUnless { it == 0 } ?: binding.otherField.getWidth()`

But I think the basic `if` is the most readable option

Maybe a personal preference, but I also prefer the positive conditions in ifs. In this case `binding.myField.getWidth() == 0` vs `binding.myField.getWidth() != 0`

<@UAN39HN81> Yeah, me too. It's not my code.

Option 3 may fail if another thread changes `myField` width between checking for 0 and returning it. This means it can return 0, something that this `if` statement is trying to prevent.
