Hi, here you can read about it [it-implicit-name-of-a-single-parameter](https://kotlinlang.org/docs/reference/lambdas.html#it-implicit-name-of-a-single-parameter)

I think they can explain it better than I can but I will try. In conventional programming when you loop through a collection you might do:  
` for (element in collection) { println(element) }`

When using Kotlin functional features you can do something like:  
`collection.map { println(it) }`

Which is equivalent to the code above
