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.
