Promises vs Async/Await

Developers should learn Promises to manage asynchronous tasks like API calls, file I/O, or database queries without falling into 'callback hell' meets developers should learn async/await when working with i/o-bound operations, such as network requests, file system access, or database queries, to avoid blocking the main thread and improve application responsiveness. Here's our take.

Promises

Nice Pick

Developers should learn Promises to manage asynchronous tasks like API calls, file I/O, or database queries without falling into 'callback hell'

Pros

• They are essential for modern web development, especially when working with frameworks like React or Node
• Related to: javascript, async-await

Cons

• Specific tradeoffs depend on your use case

Async/Await

Developers should learn async/await when working with I/O-bound operations, such as network requests, file system access, or database queries, to avoid blocking the main thread and improve application responsiveness

Pros

• It is particularly useful in web development for handling API calls, in server-side applications for managing concurrent tasks, and in any scenario where performance and scalability are critical, as it helps manage complex asynchronous workflows more cleanly than traditional callback or promise-based approaches
• Related to: javascript, promises

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Promises if: You want they are essential for modern web development, especially when working with frameworks like react or node and can live with specific tradeoffs depend on your use case.

Use Async/Await if: You prioritize it is particularly useful in web development for handling api calls, in server-side applications for managing concurrent tasks, and in any scenario where performance and scalability are critical, as it helps manage complex asynchronous workflows more cleanly than traditional callback or promise-based approaches over what Promises offers.

The Bottom Line

Promises wins

Developers should learn Promises to manage asynchronous tasks like API calls, file I/O, or database queries without falling into 'callback hell'
