The value passed to the promiseB’s then handler will be the result of the promise Armed with this understanding, you can make sense of the following: promiseB = promiseA.then (function (result) { return result + 1; }); The then call returns promiseB immediately. When promiseA is resolved, it will pass the result to promiseA’s success handler.

Javascript: How to access the return value of a Promise object
What is a Promise in Javascript A Promise is an object representing the eventual completion or failure of an asynchronous operation. A Promise may be in one of the following states: pending; fulfilled; rejected; One of the most widely used examples of asynchronous operations in Javascript is a Fetch API. The fetch() method returns a Promise.

A JavaScript Promise object can be: Pending Fulfilled Rejected The Promise object supports two properties: state and result. While a Promise object is pending (working), the result is undefined.

The then chain will execute whenever the Promise resolves. You can see that in more detail in returnPromise. Here we return a new Promise. The body of the Promise calls the resolve method when it is done (in this case that is instantly), triggering the Promise to resolve and execute all then methods chained to the Promise. Usually the Promise won’t resolve instantly, but will perform an async task (e.g. retrieving data from a server) first.

We used the Promise.resolve () method to get an example promise. We called the then () method on the Promise object to resolve the promise. The function we passed to the then () method gets called with the resolved value as a parameter. We can access this value in the body of the function. Notice that we also used the catch () method.

There are 3 ways for solving this: Since you return a promise, use .then to get the returned value. In one of the .then you already have, set an outside variable to the value. However this solution is not good since you could encounter situation where myValue is not set.

Yes, The promise returned by makeGeoCodingRequest will have the same value of the return value inside your promise.then handler. You can reject by returning something like Q.reject (new Error (Http request failed + data.status)) – Willem D’Haeseleer Aug 27, 2014 at 15:23 1 Thank you for the answer,everything works,including Q.reject.

Let’s try it. function getResult() { return getPromise() .then(function(response) { return response; }) } getResult() .then(function(result) { console.log(result); }) Now you are able to return data from JavaScript promise.
