It also provides the functionality to re-run the same lines of code again and again but has certain advantages that help to reduce the code and make it easy to use for the programmers and the developers. ContentsI. It also helps us to increase the efficiency of the code. 87. With Kotlin, we can write loop for(i in a..b){} and we could also do (a..b).forEach{}. Kotlin for each loop also does the same work for us. https://kotlinlang.org/docs/reference/returns.html#return-at-labels. Kotlin While loopsIII.
