Title rewritten to: "(ES6) Class (ES2017) Async/Await Getter Method"

Question

Is it possible or possible in the future to return a value from an ES6 class's getter via ES2017's await/async functions.

class Foo {
    async get bar() {
        var result = await someAsyncOperation();

        return result;
    }
}

function someAsyncOperation() {
    return new Promise(function(resolve) {
        setTimeout(function() {
            resolve('baz');
        }, 1000);
    });
}

var foo = new Foo();

foo.bar.should.equal('baz');

Answer 1

Update: As others have pointed out, this doesn't really work. @kuboon provided a nice solution below.

You can do this

class Foo {
    get bar() {
        return (async () => {
            return await someAsyncOperation();
        })();
    }
}

This is the same as the code below

class Foo {
    get bar() {
        return new Promise((resolve, reject) => {
            someAsyncOperation().then(result => {
                resolve(result);
            });
        })
    }
}
