Let's update the script to search for
remove(method calls in JavaScript and TypeScript files to ensure proper error handling.
Proper error handling in
removemethod is verified.The integration tests in
test/integration/document_test.tsincludeassertThrowsAsynccalls around theremovemethod, indicating that error handling is being tested and managed appropriately.

The following scripts were executed for the analysis:
Script:

760-775: EnsureprocessNexthandles rejections properly.The
processNextmethod processes tasks sequentially. Ensure that tasks handle rejections properly to avoid unhandled promise rejections.Verification successful
Verification successful:
processNexthandles rejections properly.The
enqueueTaskmethod ensures that tasks enqueued in thetaskQueuehandle rejections by catching errors and invoking therejectfunction. This confirms that theprocessNextmethod will process tasks with proper error handling.

289-327: Ensure proper error handling inattach.The
attachmethod uses.catchto log errors and rethrow them. Ensure that the caller of this method handles these errors appropriately.Verification successful
No issues found with error handling in the
attachmethod usage.The
attachmethod is not called in the main application logic files, excluding tests and examples. Therefore, the existing error handling within theattachmethod itself is sufficient for its current usage.

752-765: Good test case for sequential request handling!The test case effectively verifies that each request is handled sequentially by creating multiple clients and documents, and ensuring they are processed one by one.

What this PR does / why we need it?
Add taskQueue to handle each request one by one
When using JS SDK in environments like React, it is possible to assign Client to React Components. However, when Component Unmount is executed by moving location, resources like
yorkie.Clientneed to bedeactivatedoryorkie.Documentneed to bedetached. The challenge arises when it is not possible to await asynchronous requests while deactivating one by one due to some reasons.To address this issue, this commit introduces a task queue in
Clientto handle all requests one by one, ensuring proper deactivation or detachment.Any background context you want to provide?
