What are the potential difficulties or disadvantages of using GlobalScope in Kotlin Coroutines?

Using GlobalScope in Kotlin Coroutines is associated with several potential issues:

• Lack of lifecycle control: Coroutines launched in GlobalScope live until completion, regardless of the lifecycle of components (e.g., Activity or ViewModel in Android). This can lead to memory leaks or code execution after the component is destroyed.

• Difficulties with cancellation: Since GlobalScope is not tied to a specific context, canceling a coroutine becomes more difficult, which can result in unwanted background task execution.

• Lack of structured concurrency: GlobalScope violates the principle of structured concurrency, which helps manage coroutine hierarchy and their cancellation.

Therefore, it is recommended to use more local scopes, such as lifecycleScope in Android or create your own CoroutineScope tied to the lifecycle of an object.
