using a handful of simple functions. You’ll learn why most JavaScript developers approach asynchronous programming the wrong way, and how to avoid these common mistakes. By the end of this course, you will know
Here, the developer should have written button1_Click as an async method and then await-ed the Task instead of using its synchronous Wait method. The Wait method has its important uses, but it’s almost always wrong to use it for waiting in a UI thread like this. The Wait method won’...

The functions in this module keep track of what's going on so that you can figure out what happened when your program goes wrong. They generally return an object describing details of the current state. If your program goes wrong, you have several ways of getting at this state:...
to understand how the feature works. Not only that, but it can also be very easy to get wrong once you go outside the common happy paths for which you might use it. In this course, Brandon Minnick will teach you everything you need to know to master asynchronous programming using async...
“red” part of the loop ensures the unit test will fail when the code is incorrect. At first, testing code that you know to be wrong sounds ludicrous, but it’s actually quite important because you must be sure the tests will fail when they need to. The red part of the TDD loop ...

.catch(error => console.error('something went wrong', error)) Having a native way to create asynchronous tasks and a clear interface to follow up its possible results enabled the industry to move out of the Observer Pattern. Promise-based ones seemed to solve the unreadable and prone-to-err...
out::println, Throwable::printStackTrace);Sometimes, a suffix is added to avoid logical ambiguities that may compile but produce the wrong type in a flow:Flowable<T> merge(Publisher<? extends Publisher<? extends T>> sources); Flowable<T> mergeArray(Publisher<? extends T>... sources);...
2, which causes the app to send wrong messages. The pivot is a read access to the message text in an asynchronous procedure invoked on a background thread that conflicts with a write access in the double click event. A similar violation occurs in another user input sequence where the user...
