返回承诺的“纯”值

Question

有没有办法获得Promise的“纯”价值？

    function getData() {

        var promise = Promise.resolve([1, 2, {a:2,b:3}]);

        var wantToBeAMan;

        promise.then(value => wantToBeAMan = new Array(value));

        console.log(wantToBeAMan);
        
        return wantToBeAMan;

    }
