how does Redux Saga handle multiple concurrent tasks more efficiently than Redux Thunk

1. Concurrency Control: Redux Saga provides built-in concurrency control using the `takeEvery` and `takeLatest` functions. These functions allow you to manage multiple concurrent tasks by specifying how they should be handled. For example, `takeEvery` ensures that each task is executed sequentially, while `takeLatest` ensures that only the latest task is executed[1][2][4].

2. Task Cancellation: Redux Saga allows you to cancel tasks that are no longer needed. This is particularly useful when dealing with long-running tasks or tasks that are no longer relevant. Sagas can be cancelled using the `cancel` function, which stops the execution of the saga and releases any resources it was using[1][2][4].

3. Error Handling: Redux Saga provides better error handling than Redux Thunk. Sagas can catch and handle errors using the `catch` function, which allows you to specify a callback to handle the error. This makes it easier to manage errors and prevent them from propagating up the call stack[1][2][4].

4. Testing: Redux Saga is easier to test than Redux Thunk due to its purely functional nature. Sagas can be tested using unit tests, which makes it easier to ensure that they are working correctly[1][2][4].

5. Performance: Redux Saga is generally more efficient than Redux Thunk because it uses generator functions, which are more lightweight and efficient than promises. This makes it better suited for handling complex asynchronous scenarios and large-scale applications[1][2][4].

In summary, Redux Saga handles multiple concurrent tasks more efficiently than Redux Thunk by providing concurrency control, task cancellation, better error handling, easier testing, and improved performance.
