Race to the Finish Line
2015-10-29
Given a list of tasks, we need to know as soon as a single one of them is complete Promise.all allowed us to wait for all.

Promises Versus Events
2015-10-29
Most older JavaScript libraries deal exclusively in events when handling asynchronous processes. Here, we will compare the pros and cons of each.

The Pitfall of No Return
2015-10-29
As we will show in an example, not returning any value within a .catch can lead to unexpected behavior.

Make It All Asynchronous
2015-10-29
When a function needs to return a promise, for example, a service that's returning to a controller, but the return value is not guaranteed to be a promise, $q.when can be used to ensure that the return is indeed a promise.

Series Flow - with a Twist
2015-10-29
In some cases, we do not know how many times a particular asynchronous task is expected to be run before stopping it. Using promises, we will be able to handle "n" tasks in a series.

Interdependent Tasks
2015-10-29
Sometimes, several tasks need to be completed before a process can move on. A solution to this issue is to complete them one after the other.

Parallel and Independent Tasks
2015-10-29
More than one action is needed and wherever possible, it is better to complete these actions in parallel without having to wait for the other to complete. We will use two API calls and display data in a simple case where the calls are independent of each other.

Turning Failure into Success
2015-10-29
In the same vein as the previous video, this will cover cases where a certain block of a process needs to be transformed from a failure into a success. Promises allow us to do this by returning anything but a rejected promise.

Changing Successes into Failure
2015-10-29
When abstracting processes in general and not only asynchronous ones, we make an assumption as to what successes and what failures are. Promises make it very easy to switch from a success to a failure in the next promise, and we will learn how to accomplish this.

Making API Data User-ready
2015-10-29
Promises that represent one action resolve with a certain value. This value may be suitable for one flow, but not for another.

Chaining Promises
2015-10-29
JavaScript applications are becoming more powerful and complex, and so are corresponding asynchronous flows. Promises help controlling such flows by using chaining, which not only allows to run processes one after the other but also to alter the value that comes out of the fulfillment of this, or even the success or failure path taken by the promise.

The Future Is Coming - Angular v2 Promises
2015-10-29

Callbacks Execution and Timing
2015-10-29
A lot of processes will need to conduct more than one task upon completion of an action. Although promises are strongly single-chance and single-value, when it comes to the callbacks, developers can add as many as they want, even after the promise has been settled, and, thus, allow for several actions to be added from various parts of an application.

No Second Chance
2015-10-29
Some processes and flows require repeated information to be passed at unexpected times. Other flows, though of an unknown duration, expect their outcome to be final.

Deciding What's Next
2015-10-29
Asynchronous process flows that are handled by promises are all about clarity of code and outcomes. Here, we will learn about various ways to set callbacks for each case are success only, failure only, both success and failure.

There Are Only Two Types of Promises in This World
2015-10-29
Promises allow us to code parts of an asynchronous flow. Flows rarely follow a single direction; there are cases where things go awry.

Creating ES6 Promises
2015-10-29
Promises have become so popular that the new iteration of JavaScript ES6 implements them. This implementation is slightly different than the Angular $q service.

Make Me a Promise
2015-10-29
Some services ($http) return promise objects when called, but other processes do not. Often, a developer will need to create their own asynchronous process, such as waiting for some user interactions or the completion of a navigator action.

Promises - You've Been Using Them All Along
2015-10-29
Many processes in JavaScript are asynchronous and, thus, can be confusing for developers whose experience is mostly synchronous. Promise objects allow for a clear way to handle such processes.
