When using thread , the result is expected but when using launch from Kotlin coroutine, the result is wrong and not expected.

Code: https://pl.kotl.in/cBD4j9XWb

In the code, as expected when using the thread code in the for loop, the result prints 15000
but when using launch for loop, the result prints 0 !? which is not expected.

Why is this happening and why launch is giving wrong answer?

[ephemient]

you're blocking the executor with Thread.sleep. delay would give you the expected value.

[ephemient]

but you should not be delaying and use coroutineScope or join instead.
