Kotlin Standard Library Cookbook

Getting ready

The first step to start working with Kotlin Coroutines is to add a core framework dependency to the project:

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:0.23.3' 

The preceding code declares the kotlinx-coroutines-core dependency in a Gradle build script, which is used in the sample project (https://github.com/PacktPublishing/Kotlin-Standard-Library-Cookbook).

In the current recipe, we are going to make use of the following two functions: 

private suspend fun `calculate the answer to life the universe and everything`(): Int {    delay(5000)    return 42}private suspend fun `show progress animation`() {    val progressBarLength = 30    var currentPosition = 0    while (true) {        print("\r")        val progressbar = (0 until progressBarLength) ...
