Improved readability: Promises allow you to write asynchronous code in a synchronous-looking style, which can make your code easier to read and understand.
Better error handling: With promises, you can use the catch method to handle errors, rather than having to specify an error-handling callback function. This can make your code more concise and easier to debug.
Chaining: Promises can be chained together, which makes it easier to build complex asynchronous logic. You can use the then method to specify a callback that will be called when a promise is fulfilled and chain multiple promises together using then.
Cancellation: Promises provide a way to cancel an async operation, which can be useful in certain scenarios.
