To manage async errors, wrap code in `try...catch` blocks and attach `.catch()` handlers to promises. Consider using custom error handlers for more granular control.

Error handling in asynchronous JavaScript functions can be challenging, especially when multiple async operations are chained or when errors need to be managed across different parts of an application. To manage these effectively, start by using try...catch blocks around asynchronous code within async/await functions. This catches errors at the function level, allowing you to handle them based on the specific operation context. When using promises, append .catch() handlers to each promise chain, ensuring that any error from the promise is caught and managed. For larger applications, creating a centralized error handler can be helpful; this can log errors and return custom messages, improving both debugging and user experience. Additionally, libraries like axios for HTTP requests or express-async-errors for Express server applications offer built-in error-handling mechanisms, allowing you to streamline async error handling. Another approach is to create custom error classes that can attach more context to errors, especially when dealing with specific data operations, helping identify the error source more accurately. Finally, async error tracking tools like Sentry can monitor runtime errors, providing insights and alerts. By structuring your async code with clear error-handling paths, you ensure that even when errors arise, they’re managed predictably, improving application reliability and user experience.
