The benefits

Efficient resource utilization

Using asynchronous processing allows you to progress with other tasks during idle times. For example, instead of using sleep to wait within the timer function, you can perform other asynchronous operations during that time. This enables efficient resource utilization.

Scalability of concurrently executable processes

With asynchronous processing, you can extend the number of concurrently executable asynchronous tasks. For instance, launching multiple asynchronous timers simultaneously, allowing them to operate independently, is achievable.

Handling asynchronous events:

Using asynchronous processing simplifies waiting for and handling asynchronous events such as keyboard inputs or signals. This enables the program to react responsively to external events."

"The disadvantages

Complexity in code structure:

Asynchronous programming often introduces complexity in code structure, making it harder to read and maintain.

###Potential for callback hell
There is a risk of encountering 'callback hell' or deeply nested callbacks, making the code difficult to understand.

Debugging challenges

Debugging asynchronous code can be more challenging due to the non-linear flow of execution and timing issues.

Learning curve

Asynchronous programming may have a steep learning curve for developers unfamiliar with the concept, requiring additional skills.

Potential for race conditions

Concurrency in asynchronous programming can lead to race conditions, requiring careful synchronization mechanisms.

Increased resource usage:

While asynchronous programming can optimize resource utilization, it may also introduce overhead in managing asynchronous tasks and callbacks.

The current state does not allow resetting the timer without terminating the process, and it is also unable to be stopped.
I attempted an implementation using mpsc::channel(), but it didn't work well. It might be resolved by using an asynchronous runtime or utilizing channel() effectively.
