how to resolve that the signal being waited for is emitted by code before it returns.

I am not entirely sure I understand your question but this may help.

You can use call deferred to make sure the signal is sent at the end of the current frame like this.

call_deferred("emit_signal", "your_signal")

Or if that is not what you meant, then you can await a signal like this:

await some_object.your_signal

Or if that is not what you meant either, you may have to supply additional information so we can help.

Await in the docs:

GDScript reference

Call deferred in the docs:

Callable

call_deferred("emit_signal", "your_signal")

As you say. call deferred is a relatively good choice.

Although its not as good as Promise in JS.

Thank you very much!

Promise and call_deferred() are completely different things, you can’t compare them directly.
If you want to have a promise-like functionality, you can await a coroutine that returns a value. Check here for more information about coroutines in Godot.
