How to return [[PromiseResult]] guys, please help thankss
i use vue js and laravel
You can get that result by adding then method to the Promise. For example:
new Promise((resolve, reject) => resolve('success')).then(res => console.log(res))
This code will log your [[PromiseResult]] object.

I'm trying to better understand promises and async code in Javascript.
In doing so, I wrote the following, simple async function in the Chrome console:
const myAsync = async() => 10;
As expected, myAsync returns a promise, but when I call .then() (i.e. myAsync().then(res => res)), then console displays Promise{<fulfilled>: 10}. The promise is clearly fulfilled, but I would expect it to display, simply, the value 10.
Interestingly, if I modify the body of my call to .then() to res => alert(res), the alert displays what I expect, just 10.

Can somebody explain me how to solve this problem?
let konyvSzam=0;
db.checkPeldanySzam(rentISBN,(konyv) => {
konyvSzam=konyv.Peldanyszam;
});
console.log("Nr of books");
console.log(konyvSzam);
The variable gets the value but after I check it doesn't work
Mostly our DB call works asynchrous in node js and JavaScript try to enclose db calls in promise or use async/await .

I have a variable called LangDataService.isDataReady that is a Promise wawiting to be resolved. Upon resolve some logic will happen. How can I pass this into that Promise?
LangDataService.isDataReady.then(function () {
this.modalOn()
});
I know i can cache var self_ = this; but I'm curious of other alternatives?
LangDataService.isDataReady.then(function () {
this.modalOn()
}.bind(this));
