How can I use await method in not suspend function as like this test code: https://github.com/Kotlin/kotlinx.coroutines/blob/master/js/kotlinx-coroutines-core-js/src/test/kotlin/kotlinx/coroutines/experimental/PromiseTest.kt

It is actually in a suspending lambda in the code you linked,

promise

is a function that takes a suspending lambda (which can then call

await

).

Oh got it! thank you
