In Kotlin, all Coroutines run inside a CoroutineScope.

A scope controls the lifetime of coroutines through its job. When you cancel the job of a scope, it cancels all coroutines started in that scope.

A context that enforces cancellation and other rules to its children (Jobs) and their children recursively.

Functions used to create new coroutines such as launch()and async() extend CoroutineScope.

💡 The pattern of async-await from JS is similar to coroutines. The suspend keyword is similar to async. In Kotlin, await() is implicit when calling a suspend function.

Kotlin has a method Deferred.await() that is used to wait for the result from a coroutine started with the async builder.
