Difference Between Promise.resolve() & Promise.reject() methods in JavaScript

Promise.resolve() and Promise.reject() are both methods provided by the Promise object in JavaScript. They serve different purposes in handling asynchronous operations:

1. Promise.resolve():
   • Creates a new Promise object that is resolved with the provided value or a resolved Promise object if the provided value is already a Promise.

   Example:

   const resolvedPromise = Promise.resolve('Resolved');
   resolvedPromise.then(console.log); // Output: Resolved

2. Promise.reject():
   • Creates a new Promise object that is rejected with the provided reason.
   • Useful for creating a rejected Promise object explicitly to signify failure or error conditions.
   • Used when you want to handle error scenarios or explicitly reject a promise.

   Example:

   const rejectedPromise = Promise.reject('Rejected');
   rejectedPromise.catch(console.error); // Output: Rejected
