Tell us what’s happening:
I wrote this code for the Cash Register project. All of my results appear to be correct, but I keep failing the second and third tests. This is baffling me because I compared my results with the expected result like so…
let myResult = checkCashRegister(19.5, 20, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]])
console.log(myResult)
let fccResult = {status: "OPEN", change: [["QUARTER", 0.5]]};
console.log(fccResult)
if( JSON.stringify(myResult) === JSON.stringify(fccResult) ){console.log("they are the same")}
and it is still saying our results are different. I am stumped at this point. Any advice? Sorry for my code being such a mess.
