Error Handling with Async/Await in JavaScript

Question

Explain how to properly handle errors using async/await in JavaScript. What are the pros and cons of using try/catch compared to promise chaining?

Accepted Answer

1. Use try/catch blocks around async function calls for synchronous-looking error handling.
2. This method provides clearer, more readable code. 
3. Promises can be handled using .then() and .catch(), but this can lead to 'callback hell' in complex chains.
4. Trade-offs:
   - try/catch allows for easier debugging.
   - promise chaining can keep logic contained without additional async functions, but readability may suffer.
