Hi, could you please help me to find the succinct way of sorting two arrays? currently I have

val referenceServiceFeaturesConflicts = refResponse.serviceFeaturesConflicts
.sortedWith(compareBy({ it.addonPrecedence }, { it.sfName }))
val actualServiceFeatureConflicts = response.serviceFeaturesConflicts
.sortedWith(compareBy({ it.addonPrecedence }, { it.sfName }))

why do you want to sort both arrays with a single line?

just to make code prettier)

I expect the most readable code would be to extract the comparator to a variable if thats possible

👍 1

Otherwise it seems pretty fine to me

val sortByNameAndPrecedence: List<ServiceFeaturesConflicts>.() -> List<ServiceFeaturesConflicts> = {
            this.sortedWith(compareBy({ it.addonPrecedence }, { it.sfName }))
        }

I made a lambda)

So its now 5 lines in total ?

Two arrays in single line: listOf(v1, v2).map { it.sortedWith(yourLmbda) } 🤖

I guesses there is some elegant solution=)

Also lambda may do sort here, not just compare.

@nil2l yeah, it's one of the possible ways

thanks
