Node.js promises are used to handle asynchronous operations more elegantly, allowing for clearer error handling and easier code maintenance. They can be created using the `Promise` constructor and handled with `.then()` and `.catch()`, which can also be chained together for complex async flows.
TL;DR Async/Await is a syntax sugar that allows writing asynchronous code in a synchronous manner. It's based on promises, which are used to handle asynchronous operations. When using async/await, execution pauses until a promise is resolved or rejected, then resumes once the promise is resolved. Promises have three states: pending, resolved, and rejected, with methods for handling their state, including then(), catch(), and finally().
