Run code once the Firestore get method has completed its execution

Is it possible to execute code after the get method is finished in JavaScript, similar to how it can be done in Java (Android)?

Below is an example of my code:

mColRef.get().then(function(querySnapshot){
    querySnapshot.forEach(function(doc) {
        console.log(doc.id);
    });
});

Can I achieve something like this in JavaScript for web development? If so, how would you go about coding it?

mColRef.get().then(function(querySnapshot){
    querySnapshot.forEach(function(doc) {
        console.log(doc.id);
    });
}).OnCompleteListener(new OncompleteListener ....

Thank you for your assistance!

Answer №1

It seems like you might be complicating things unnecessarily. In JavaScript, using then() with a promise is similar to utilizing an OnCompleteListener with a Task object in Android. To simplify your code, just include the code to be executed after get() finishes inside the function being passed to then().
