This structure made error handling inconsistent and logic difficult to follow, prompting the need for a more linear approach to asynchronous flow control. Error Handling Best Practices Built on the foundation of promises, async and await provide syntactic sugar that makes asynchronous code look and behave more like synchronous code.
Understanding the Microtask Queue's Role in JavaScript Promises
then() is a rejection handler, though it is often considered better practice to use a dedicated. Alternatively, wrap await calls in try.
Pending: The initial state, indicating the operation is not yet complete. then() method to handle the fulfilled state and optionally the rejected state.
Understanding the Microtask Queue's Role in Promise Execution
catch() method at the end of a promise chain to handle any errors that occur during the process. An async function always returns a promise, and the await keyword pauses execution until a promise settles, allowing you to write linear, non-nested logic that is significantly easier to debug.
