Kotlin IntArray , Array , and emptyList()

Kotlin is a statically typed programming language known for its expressive and concise code, offering various ways to implement features, particularly through its collection classes. The language provides two main array implementations for integers: IntArray and Array, with IntArray being a primitive type offering better performance and default initialization to zero, while Array is a generic class requiring explicit value initialization. The article explores the nuances between these two, including their creation, conversion, and performance differences, and compares them to lists, which are interfaces with resizable and immutable options. Kotlin arrays support operations like getting, setting, traversing, sorting, and reversing elements, and the article provides examples of these functions, highlighting the benefits and considerations of using each array type in different scenarios.
