How to use For Loops in Kotlin | for, forEach, forEachIndexed

For Loops and the forEach function!

In this video, you're going to learn how to iterate over collections - or even more generally iterables - in Kotlin. To iterate over, for example, lists you can use the for-in loop. If you want to iterate over the indices, you can use the .indices property. Further, if you want something like a fori loop from Java, you can just use an IntRange with your for in loop. You can even iterate over the chars of a Sting with a for loop. Everything that implements the Iterable interface can be used with the in operator for for loops. If you want to have a bit more functional style, you can also use the .forEach function to iterate over the elements of a list. Finally, you can use the .forEachIndexed function to iterate over the elements with their index in a functional manner.
