Write asynchronous code that looks and feels synchronous.
Introduced in ES2017, `async/await` is syntactic sugar built on top of Promises that makes asynchronous code even easier to write and read. It allows you to manage promises in a way that looks like traditional, synchronous code, avoiding the need for `.then()` chains. The `async` keyword is used to declare a function as asynchronous. An `async` function always implicitly returns a Promise. The real magic comes from the `await` keyword, which can only be used inside an `async` function. When you place `await` in front of a Promise, it pauses the execution of the `async` function until the Promise is either fulfilled or rejected. If the Promise is fulfilled, the `await` expression returns the resolved value. If it's rejected, it throws an error, which can be caught using a standard `try...catch` block. This is a huge win for readability and error handling. Instead of a `.catch()` chain, you can use the familiar `try...catch` syntax to handle errors from multiple `await` expressions in one place. `Async/await` dramatically simplifies asynchronous logic, making it more intuitive and maintainable, and is the preferred way to work with promises in modern JavaScript.
