async functions

Async functions are a way to handle tasks that take time to complete, like loading data or fetching information from the internet, without stopping the entire program. When an async function is called, it begins its process but allows other tasks to run concurrently instead of waiting for it to finish. This makes programs more efficient and responsive, especially when dealing with multiple time-consuming operations. Think of async functions as a way to keep your program working on other things while waiting for certain tasks to complete, improving overall performance and user experience.
