为什么我的 Javascript 功能不能正常工作？

Question

In my function I am trying to figure out the amount of years you would have to save a specified amount of money before you would have a million dollars.
However my function is console.logging numbers in the thousands instead of years.

//The function I have created.
function retirement(yearsTillPaid){

//Why does it not work right?
return function(millionDollarDream){
    var goalTo = 1000000;
    var baller = goalTo / millionDollarDream;
    var amount = millionDollarDream / baller;
    var howManyYears = goalTo / amount;
    console.log(howManyYears); 
     }
  }


  //calling my function
  var retirementUs = retirement(250,000);
  var retirementNk = retirement(1);
  var retirementAu = retirement(1);
  var retirementGermany = retirement(1);

  retirementUs(250,000);
  retirementNk(140,100);
  retirementAu(333,000);
  retirementGermany(50,000);

Answer 1

Both functions expect a single Number as parameter. However they will run without error when given two.

It looks like you want to do a calculation with 250000 instead of 250 . The added comma results in two parameters: 250 and 0 .
