I need to write function that calculates the coins you would use to give a customer their change in a shop. The function takes one argument, which is the amount of change needed, in pence. The function should always return an object. for example 13p change should be returned like this:
changeCalculator(13);
// should return {‘10’:1,‘2’:1,‘1’:1}
I’m stuck (new to coding), can someone direct me on ways to go about writing the function?
function changeCalculator (num) {
var res = {};
if (num < 0) return -1;
if (num === 0) return 0;
for (var i = 0; i < num.length; i++) {
}
return res;
};
Thank you,
