andalso
require lambdas that return Unit,apply
andlet
return a value so you can also map insiderun - p

09/15/2020, 10:21 AMhmm I was looking exactly into these functions but I couldn't make them work... the distinction is a lil confusing for a beginner - p

09/15/2020, 10:22 AMthere are a good handful of articles in the wild about them, they were all the rage when Kotlin started spreading 😄 - e

09/15/2020, 10:22 AMI think for my use case I will start with apply. Ended up with:val db = SailRepository(MemoryStore()).apply { init() }👍🏼 1 - p

02/11/2022, 2:31 PMIs this a correct approach to functional way of building an object when multiple transformations/calls are necessary? Should I use a different name for each functions assuming it could be 10x more “”transformation functions” or more intermediate parameters?Copy codedata class SomeClass( a: A, b: B, c: c, ) fun buildSomeClass( result1: ResultFromHttp1, result2: ResultFromHttp2, ): SomeClass = buildSomeClass( intermediate1 = result1.transfom() intermediate2 = result2.transform() ) internal fun buildSomeClass( intermediate1: IntermediateType1, intermediate2: IntermediateType2, ) = SomeClass( a = intermediate1.a, b = intermediate2.b, c = intermediate2.c, ) internal fun ResultFromHttp1.transform(): IntermediateType1 = ... internal fun ResultFromHttp2.transform(): IntermediateType2 = ...
