Can async/await be used in constructors?

Question

As the question stated. Will I be allowed to do this:

class MyClass {
    async constructor(){
        return new Promise()
    }
}

Answer 1

In a nutshell:

1. Constructor is a function that needs to provide a concrete object.
2. Async returns a promise; exactly opposite of concreteness.
3. async constructor is conceptually conflicting.
