Synchronous is the better choice if the program's sole purpose is to run simple, sequential tasks. Data processing, for example, tolerates the stop-and-wait aspect of synchronous programming. Asynchronous code is more suitable to programs that need to respond to events, such as a graphicaluser...
More simple to mix asynchronous and synchronous code Able to avoid race conditions in code Simple to coordinate asynchronous code that depends on return values (Bonus) Works well with dependency injection in code A recommended goal is to achieve complete or near-complete Referential Transparency in ...
The previous code highlights an unfortunate programming practice: Writing synchronous code to perform asynchronous operations. The code blocks the current thread from doing any other work. The code doesn't interrupt the thread while there are running tasks. The outcome of this model is similar to ...
Some routine processes, such as loops and exception handling, can be difficult to handle in traditional asynchronous code. In an async method, you write these elements much as you would in a synchronous solution, and the problem is solved. For more information about asynchrony in previous ...
need your code to be more asynchronous. Writing asynchronous code has traditionally involved installing a callback (also called continuation) to express the logic that occurs after the asynchronous operation finishes. This complicates the structure of asynchronous code as compared with synchronous code....

Synchronous Programming Model 1. Single Threaded A thread is assigned to one task and starts working on it. Once the task completes then it is available for the next task. In this model, it cannot leave the executing task in mid to take up another task. ...

Convert synchronous code into asynchronous In a call to a function which takes a callback with parameters(error, result), the callback argument could be represented as%%, andlatterexpressions and statements will become the body of the callback. Theformerandlatterrelationship is determined by the ...
