Promisify a function

[nitish24p]

Given a function as mentioned below. Write a utility, promisify, where the usage is as explained below

function asyncFunction(a, b, callback) {
  const isError = Math.random() > 0.7;
  setTimeout(() => {
    if (isError) {
      callback(null, new Error("Something went wrong"));
      return;
    }

    callback(a + b, null);
  }, 3000);
}

function promisify(fn) {
  // Implement Code here
}

// Old ussage
asyncFunction(1,2, function(result, err) {
  console.log(result,err)
})


// New Usage
const promisifiedFn = promisify(asyncFunction);
 promisifiedFn(1, 2)
   .then(res => {
     console.log("result", res);
   })
   .catch(console.log);
