The code does not return a value directly or instantly. Instead, it returns a promise to give the value at some point in the future. In JavaScript, a promise is asynchronous, which means it takes time to resolve or complete. It takes time to find the applicant's resume, just as it takes time to find the applicant's résumé.

The Promise constructor accepts a function (an executor) that will be executed immediately and two functions: resolve and reject, which must be called when the Promise is resolved (passing a result) (passing an error).

In JavaScript, promises are used to handle asynchronous operations. When dealing with several asynchronous activities, where callbacks might lead to unmanageable code, they are simple to manage.

Object literal syntax is the most popular method: color: 'blue,' type:'sedan,' doors: '4', const myCar = You could also construct a class and use the new keyword to instantiate it. A promise, like the later example, is simply an object that we construct.

The initial state is pending:

fulfilled: signifies that the operation promised was completed successfully.
rejected: denotes that the promised operation did not go as planned.
