When synchronous programming is employed and tasking is sequential, latency in the interface causes the application to hang due to demand side issues. The issue with this scenario is that the user interface frequently freezes for extended periods of time when doing tasks like file input-output or network queries, which are infrequent but very important for assessing the performance of interactive applications.

The benefit of asynchronous programming is that no blocking occurs since actions are not performed sequentially; yet, avoiding blocks in the code is not always easy. Even if they are efficient, problems like race situations and callback hell can develop and cause poor code management, maintenance, and debugging.

I am expecting details explaination regarding synchronous and asynchronousprogramming language.
