In JavaScript, promises are a way to handle asynchronous operations, and the async/await syntax is a more readable approach to working with them. The correct approach to resolving promises using async/await is by wrapping the promise in an async function. When a function is defined with the async keyword, it automatically returns a promise, and within that function, you can use the await keyword to pause the execution until the promise is settled (either resolved or rejected).

Using await before a promise lets you write asynchronous code that looks synchronous, making it easier to read and maintain. This approach allows you to handle the resolved value of the promise directly, as if it were a standard return value from a synchronous function. For example, if you have an asynchronous function that fetches data, you would define it with async and use await to get the data when it is ready.

This method of handling promises is preferred in modern JavaScript development because it simplifies error handling with try/catch blocks and reduces the complexity associated with traditional promise chaining using then() calls. In summary, wrapping the promise resolution in an async function and using await is the correct and recommended way to work with promises in JavaScript.
