Suspension functions

Suspension functions are a feature in programming, especially in Kotlin, that allow code to pause and wait for long-running tasks (like fetching data from the internet) without blocking the entire program. When a suspension function is called, it temporarily pauses its execution and frees up resources, allowing other tasks to run smoothly. Once the task completes, it resumes where it left off. This approach makes programs more efficient and easier to write, especially for handling asynchronous operations, since it simplifies managing complex workflows without the need for extensive threading or callback mechanisms.
