Promises are easier to write with Async/Await. When you use the keyword 'async' before a function, it always returns a promise. Inside async functions, the term await is used to make the program wait until the Promise resolves.

An asynchronous function is defined with the async keyword, which returns an AsyncFunction object. The await keyword is used to halt async function execution until a Promise is resolved or rejected, and then to resume execution after the Promise is resolved or refused.

Promise is an object that represents an interim state of an operation that will be completed at some point in the future. Async/Await is a promise wrapper, a syntactic sugar that makes programs run more synchronously.
