Map the Debris: this code is working in jsbin but why not passing the test

Tell us what’s happening:

Your code so far

function orbitalPeriod(arr) {
  var GM = 398600.4418;
  var earthRadius = 6367.4447;
  let h;
 for(let i =0; i< arr.length; i++){
   h = arr[i].avgAlt;
   arr[i].avgAlt = Math.round(2*Math.PI*Math.pow(h+earthRadius,1.5)/Math.sqrt(GM));
  return arr;

orbitalPeriod([{name : "sputnik", avgAlt : 35873.5553}]);

Link to the challenge:

Your code does not work in JSBin either, because the result for orbitalPeriod([{name : “sputnik”, avgAlt : 35873.5553}]) should be:

 [{name: "sputnik", orbitalPeriod: 86400}]

and your function returns:

[{name: "sputnik", avgAlt: 86400}]
