Mastering Kotlin

Coroutine primitives

There are several fundamental concepts to understand when working with Kotlin coroutines. To highlight these, we can look at our example from the previous section:

fun main() {    GlobalScope.launch {        delay(500)        println("Coroutines")    }    println("Hello")    Thread.sleep(1000)}

Within the preceding snippet, there are examples of three key concepts:

• Coroutine scopes
• Coroutine builders
• Suspending functions

Let's examine each of these in detail in the coming sections.
