How has error handling in async code evolved in recent JS versions?

Error handling in asynchronous JavaScript code has significantly evolved over the years. Originally, callback methods were used to manage asynchronous operations, leading to complicated error handling and "callback hell." This approach made it difficult to manage errors effectively. With the introduction of Promises in ES6, developers gained a cleaner way to handle asynchronous operations and errors. Promises provide a `catch` method, allowing for clearer and more manageable error handling.

In the latest versions of JavaScript, especially with the introduction of async/await in ES2017, error handling has reached a new level of simplicity. This syntax allows developers to write asynchronous code that looks and behaves like synchronous code, making error handling as straightforward as using try/catch blocks. This shift has greatly improved code readability and maintainability.
