A modern programming language that makes developers happier.

kotlinlang

`?.` vs `if` Which one is better in the following example and why? (open to improvements)

```
if (variant is TestedVariant &amp;&amp; variant.testVariant != null) {
	renameAPK(variant.testVariant)
}
```

```
(variant as? TestedVariant)?.testVariant?.let(::renameAPK)
```

it reads way more straightforwardly, the second one is awkward af, regardless of how familiar you are with Kotlin

ALTHOUGH ALTHOUGH ALTHOUGH if you don’t want to cast juse use the `?.`

<@UA001QPFG> I'm not sure I get you, I need the cast as `variant: ApkVariant` doesn't have the field `testVariant`

btw, after looking at this again with a fresh mind I went with:
```
if (variant is TestedVariant) {
	variant.testVariant?.run(::renameAPK)
}
```
because it's still readable, but less repetitive than :one:
