Answer

Async/await provide a more synchronous-like structure to asynchronous code, making it easier to read and understand. Benefits include:

  • Improved readability: Code flows linearly, resembling synchronous code.
  • Error handling: Use try/catch for cleaner error handling compared to .catch() methods in promises.
  • Debugging: Stack traces are easier to follow.
  • Use cases: Ideal for sequential asynchronous operations, where one task depends on the result of another.
