Can you explain what the coroutineScope function in Kotlin means and what it is used for?

The coroutineScope function in Kotlin creates a new coroutine scope and suspends the execution of the current coroutine until all child coroutines within this scope complete. This allows structuring asynchronous code, ensuring that all tasks launched inside coroutineScope are completed before the external code continues.

Example usage:

suspend fun loadData() = coroutineScope {
    launch { fetchFromNetwork() }
    launch { fetchFromDatabase() }
    // coroutineScope will wait for both launches to finish
}

Thus, coroutineScope helps manage the lifecycle of coroutines and guarantees that all child operations complete correctly, which is important for preventing leaks and errors in asynchronous code.
