How do I remove the promise and make it a normal array-CodePudding

In my JavaScript learning journey, I encountered a complex problem that lasted more than 24 hours to research and try several published solutions, but unfortunately, I did not succeed in solving my problem. Which tempted me to write this reply to solve this complex problem for me!

class db{
    async findOne(search){
        try {
            const doc = this.collection.doc(search).get();
            return get.data()
        } catch (error) {
            console.error(Error(red(error)).message);
            process.exit(1)
        }
    }
}

Output

Promise { <pending> }

What I really want is for the output to be done without using then and be like the following output:

{
  name:'Johan',
  age:'15',
}

Is this this.collection.doc(search).get(); synchronous, i guess it's not.

so, const doc = await this.collection.doc(search).get();

this will solve your problem.

CodePudding user response：

You have to use await it wait on the specifix line until it finish Here you go!!

const doc = await this.collection.doc(search).get();

CodePudding user response：

If you are getting arrays of promises you can resolve them by using promise.All([Array of promises]);

Promise.all([promise1, promise2, promise3]).then((values) => {
console.log(values);
});
