suspend functions

Suspend functions are a feature in programming, particularly in Kotlin, designed for asynchronous programming. They allow a function to pause its execution and free up resources, enabling other tasks to run concurrently without blocking the entire program. This is especially useful when dealing with operations that take time, like network requests or file processing. When a suspend function is called, it can "suspend" its work to wait for a result, then resume when the result is ready, leading to more efficient and responsive applications. It's a way to manage time-consuming tasks while keeping the program responsive.
