What is an effective method for managing asynchronous calls in SFCC?

Employing promises or callbacks is a highly effective method for managing asynchronous calls in Salesforce Commerce Cloud (SFCC). In a web development environment like SFCC, handling asynchronous operations is crucial to ensure that the application remains responsive and efficient.

Promises and callbacks allow developers to work with these operations without blocking the execution of code. For instance, when making an API request or performing I/O operations, using a promise can enable handling the result of the operation once it is completed, allowing the rest of the code to execute in the meantime. This makes the application more performant and user-friendly, as it can continue processing other tasks while waiting for the asynchronous call to complete.

In contrast, relying solely on synchronous functions or running all code synchronously can lead to performance bottlenecks. When tasks are executed in a synchronous manner, other processes must wait for each task to finish before starting, which can hinder application responsiveness and user experience. Debugging tools, while useful for tracking down issues, do not directly handle asynchronous calls; therefore, they are not a method for managing them effectively.
