Which method is used to resolve promises?

• A. Promise.resolve()
• B. Promise.then()
• C. Promise.all()
• D. Promise.finally()

Answer: (A)

The method used to resolve promises is Promise.resolve(). This method is particularly useful when you need to create a promise that is resolved with a specific value immediately. By using Promise.resolve(), you can convert any value into a promise that is considered resolved, allowing you to work with it in a consistent manner, as if it were a promise from the beginning. When you call Promise.resolve(value), if the value is a promise, it will return that promise; if it is not, it will create a new resolved promise with that value. This capability makes it easy to ensure that you're working with promises, facilitating smoother chaining and error handling in asynchronous operations. The other methods serve different purposes in regards to promise handling. Promise.then() is used to attach callbacks to be executed when a promise is resolved or rejected but does not directly handle resolving promises. Promise.all() is designed to take an array of promises and return a single promise that resolves when all of the promises in the array have resolved or one of them rejects. Promise.finally() is used to execute a final block of code after a promise has settled, regardless of its outcome, but does not resolve a promise itself.
