There are 5 chapters in this course.

In chapter 1, get a solid understanding of what is #coroutine in #kotlin.
- Basics of coroutine builders: launch, async, and runBlocking.

In chapter 2, dive deeper into Coroutine Builders and explore them in detail.
- Use GlobalScope companion object to launch coroutines.
- Why GlobalScope is discouraged to use?
- Test suspending functions by writing a JUnit test case.

In chapter 3, learn to cancel coroutines and handle exceptions.
- What is cooperative coroutine? How to write a cooperative code?
- Use of yield() and delay() suspending functions (suspend modifier).
- Handle CancellationException and TimeoutCancellationException.
- Use withContext(NonCancellable), withTimeout, and withTimeoutOrNull coroutine builders

In chapter 4, compose suspending functions in different ways within a coroutine.
- Explore how code execution in coroutine is sequential by default.
- How to execute suspending functions in a coroutine concurrently?
- Lazily execute async coroutine by using CoroutineStart.LAZY

In chapter 5, learn a few advanced coroutine concepts.
- Understand what is CoroutineScope?
- What is CoroutineContext?
- What is a Dispatcher?
- Role of a dispatcher: to assign a thread to a coroutine.

Hello Sriyank I am very happy and I would like to say thank you a lot. I had a hard time understanding coroutines at work. Now that I have watched your video is is very clear because you are a really really good teacher, you start from the basics and then get more and more difficult slowly. And the video is really good you always show what you are talking about with arrows and boxes and so on. So again thank you a lot and many greetings and best wishes from Switzerland! Regards, Marcel
