  //Inside the order function, when the time delay is completed (i.e., after 2000 milliseconds), it calls resolve(work()). Here, work() is the callback function . So, in this context, resolve is saying that the work represented by () => console.log(${stocks.Fruits[0]} was selected) has been successfully completed, and any subsequent .then callbacks will be executed.
