Asynchronous code

Asynchronous code is a type of program that performs tasks without waiting for the result from the first task. It’s used to speed up the process by running multiple tasks at once, which makes it more efficient.

In the other hand Synchronous code is a type of program that waits for the result from the first task before executing another task. It’s mostly used when we need feedback from a system in real time and every millisecond counts.

Handling asynchronous code is essential for many programming languages and is crucial for a web application.

The use of asynchronous code increases an application's responsiveness by freeing up the thread of execution so that it can handle other tasks while waiting on an external process to complete. However, it also introduces new problems for the programmer to solve, such as how to avoid race conditions and deadlocks.
