 [//]: # (title: Arrays)
 
-An array is a data structure that holds a fixed number of values of the same type or its subtypes. 
-The most common type of array in Kotlin is the object-type array, represented by the [`Array`](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-array/) class.

 ## When to use arrays
 
+* TODO:
 Use arrays in Kotlin when you have specialized low-level requirements that you need to meet. For example, if you have 
 performance requirements beyond what is needed for regular applications, or you need to build custom data structures. If
 you don't have these sorts of restrictions, use [collections](collections-overview.md) instead.
