Get promisevalue from promise object

Whatever is returned in a then() method will get passed as the first parameter to the next then() method. It can be a scalar value (Number, Boolean, String, etc.), an object, or another Promise. The infrastructure will automatically wrap non-Promise values into a Promise value so that they can be chained. The operation behaves as though set_value, set_exception, set_value_at_thread_exit, and set_exception_at_thread_exit acquire a single mutex associated with the promise object while updating the promise object. An exception is thrown if there is no shared state or the shared state already stores a value or exception. This functions resolve the single promise object when all promise objects passed to the function are resolved. ASP.NET Web API implementation The article uses an ASP.NET Web API service created using the free Visual Studio 2015 Community edition .

If target is provided, deferred.promise() will attach the methods onto it and then return this object rather than create a new one. This can be useful to attach the Promise behavior to an object that already exists. If you are creating a Deferred, keep a reference to the Deferred so that it can be resolved or rejected at some point. Futures provide a way to reason about performing many operations in parallel– in an efficient and non-blocking way. A Future is a placeholder object for a value that may not yet exist. Generally, the value of the Future is supplied concurrently and can subsequently be used. service.setup(app, path) -> Promise is a special method that initializes the service, passing an instance of the Feathers application and the path it has been registered on. For services registered before app.listen is invoked, the setup function of each registered service is called on invoking app.listen. When the promise is still pending, then test.get('isPending') will be true. And once the promise has been fulfilled, then the template can show the value from the promise result. You'll first need to create a new object that uses ObjectProxy and extends...

Note: The returned Promise is linked to a Deferred object stored on the .data() for an element. Since the.remove() method removes the element's data as well as the element itself, it will prevent any of the element's unresolved Promises from resolving. One of the rules of promises is that you either return the promise chain to the caller, or handle errors, but not both. (You might convert an error to another kind of error, but you don't convert it to a resolution unless you can actually fix the problem.).

Message {channelId: string, type: string, summary: string, participantId: string, createdAt: Date, payload: MessagePayload, metadata: Object} Return promise, assign promise to variable, pass around and use its then methods to access resolved data. regex - JMeter extract with regular expression a javascript event value. regex - Regular expression get IMG SRC from HTML.commentCount is going to return a promise,..
