Can Async/Await and .then().catch() Work Together for Efficient Asynchronous Code?

Asynchronous Programming with Async/Await and .then().catch()

When working with asynchronous code, developers often encounter the dilemma of choosing between async/await and .then().catch(). Both approaches offer ways to handle asynchronous tasks, but can they be combined for optimal results?

Using Async/Await and .then().catch() Together

Consider the following code snippet:

Here, the async/await syntax is used to pause the function execution while waiting for the result of anotherCall(). However, .then().catch() is also employed to handle errors or perform additional transformations.

Potential Issues

While using async/await and .then().catch() together may seem convenient, it can introduce some potential issues:

• Unnecessary Indentation: The combination creates unnecessary indentation levels, making the code less readable and maintainable.
• Mixing Promises and Async/Await: Using .then().catch() involves working with Promises, while async/await uses a different syntax and error handling mechanism. This can lead to confusion and unexpected behavior.

A Better Alternative: Async/Await and try/catch

To avoid these issues, it is recommended to use async/await with try/catch instead of .then().catch(). This approach ensures a clean and concise code structure while maintaining error handling capabilities.

In this example, the try/catch block handles any errors thrown by anotherCall() and provides a centralized location for error handling.
