What is the difference between launch/join and async/await in Kotlin coroutines?

Hi everyone! I started learning coroutines in Kotlin and got confused about two approaches: launch/join and async/await. They both seem to allow running tasks in parallel and waiting for their completion, but I don't understand when to use which. I have a simple example: I need to download two files and merge them. I tried both approaches, but the results are different. First approach with launch/join: ```kotlin fun main() = runBlocking { var result1 = "" var result2 = "" val job1 = launch { delay(1000) result1 = "File1 content" } val job2 = launch { delay(1000) result2 = "File2 content" } job1.join() job2.join() println("$result1 $result2") } ``` Second approach with async/await: ```kotlin fun main() = runBlocking { val deferre ```
