Promise Batch for SDE interview | Javascript Coding Round | Question 1

In JavaScript, Promises are used to represent asynchronous operations. When working with multiple asynchronous tasks, managing them individually can become cumbersome and inefficient. Promise batches offer a structured approach to group and handle these tasks collectively.
Key Concepts and Benefits:
Grouping: Promise batches allow you to group related asynchronous operations together, providing better organization and maintainability.
Sequential Execution: You can configure promise batches to execute promises sequentially, ensuring that one promise completes before the next one is started. This is useful when tasks have dependencies or need to be performed in a specific order.
Parallel Execution: Alternatively, promise batches can execute promises in parallel, taking advantage of multiple cores or threads to speed up execution. This is ideal when tasks are independent and can be processed simultaneously.
Error Handling: Promise batches provide mechanisms to handle errors that occur within individual promises. You can implement strategies to catch and manage errors gracefully, preventing the entire batch from failing.
Improved Performance: By optimizing the execution order and handling errors efficiently, promise batches can contribute to better overall performance in your JavaScript applications.
