(ES6) class (ES2017) async / await getter

by

Update: As others have pointed out, this doesn’t really work. @kuboon has a nice workaround in an answer below here..

You can do this

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

which again is the same as

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