Kotlin and idiomatic way to write, 'if not null, else…' based around mutable value

Question

Suppose we have this code:

class QuickExample {

    fun function(argument: SomeOtherClass) {
        if (argument.mutableProperty != null ) {
            doSome         


        

Answer 1

i usually write it like this:

  takeIf{somecondition}?.also{put somecondition is met code}?:run{put your else code here}

note the question mark after takeIf is a MUST. you can use also or apply keyword.
