What is the contrast between utilizing async/await and promises?

edit

Async/await and promises are both used to write asynchronous code in JavaScript. However, there are some differences between them:

1. Ease of use: Async/await is generally considered easier to use and read than promises because it allows you to write asynchronous code in a synchronous-like manner.

2. Error handling: When using promises, you need to handle errors using .catch() or try/catch blocks. With async/await, you can use try/catch blocks to handle errors, making it more intuitive to handle exceptions.

3. Chaining: Promises are chainable, meaning you can easily combine multiple asynchronous operations together. Async/await is not chainable, but you can write asynchronous code that looks like it's synchronous, making it easier to understand and follow.

4. Debugging: Async/await can be easier to debug than promises because it provides better stack traces and error messages.

In summary, while both async/await and promises can achieve the same result, async/await is generally considered easier to use, read, and debug, while promises are more versatile and can be more powerful for chaining multiple operations.
