What is async?
Understand the Problem
The question is asking about the concept of 'async', which typically refers to asynchronous programming or operations where tasks can run independently of the main program flow, often allowing for better performance in I/O-bound or high-latency operations.
Answer
Asynchronous programming (async) allows multiple tasks to run concurrently, improving performance and responsiveness by not blocking the main thread.
Asynchronous programming (async) is a method of programming that allows multiple tasks to run concurrently, without waiting for previous tasks to complete. It is often used to perform network requests, file operations, or other I/O-bound tasks without blocking the main thread, improving performance and responsiveness.

It is often used to perform network requests, file operations, or other I/O-bound tasks without blocking the main thread, improving performance and responsiveness.
More Information
Async is particularly useful in applications that involve waiting for external resources, such as data from a server or user input.
Tips
A common mistake is not handling errors properly in async functions, which can lead to unhandled promise rejections in JavaScript or similar issues in other languages.
