Question
Complete the function promiseMeSuch that it takes a number as the first argument (time) and a string as the second argument(data).It returns a promise which resolves after time milliseconds and data is returned.Note:- You only have to implement the function, in the example itshows your implemented question will be run.InputFunction should take number as first argument and data to be returned as second.OutputResolves to the data given as inputExamplepromiseMe(200, 'hi').then(data=>{console.log(data) // prints hi})
Solution
Here is the JavaScript function that fulfills your requirements:
function promiseMe(time, data) {
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve(data);
}, time);
});
}
This function creates a new Promise. The Promise constructor takes one argument, a callback with two parameters, resolve and reject. Here we are using the setTimeout function to simulate asynchronous behavior. After the specified time in milliseconds, the promise will be resolved with the given data.

This problem may have one or more correct answersIf you want to execute a function right after the return of some other function, then callbacks can be used.A function passed to another function as an argument is referred to as a callback function.A callback function can run before another function has finished.None of these.
