2. Built-in Immutable Collections One of the approaches is to use Kotlin’s default mutable and immutable collections. As an example, let’s take a look at MutableList and List. First, we’ll create a mutable list and add an element to it: val mutableList = mutableListOf<String>() mutab...

chapters, you learned many techniques to help you write safer programs. Most of these techniques come from functional programming. One of these techniques consist in using immutable data to avoid state mutations. Programs without mutable states are safer, more reliable, and easier to design and ...
