Can someone please help me with this challenge.The loan needs to be calculated. Amount is 15000 and percent is 20.

Question

function main() {
//get the initial amount and the interest percentage
var amount = parseInt(readLine(),10);
var yearPercent = parseInt(readLine(),10);

var loan1 = new Loan(amount, yearPercent);

//output to console
console.log(loan1.yearIncome());
}

function Loan(amount, percent, yearIncome) {
this.amount = amount;
this.yearPercent = percent;
//your code goes here
this.yearIncome = function() {
this.yearIncome = calcYearIncome()
}

};

function calcYearIncome(amount,percent,yearIncome){
//complete the function to calculate yearly income

this.amount = amount;
this.yearPercent = percent;

this.yearIncome = function(amount,percent){
return this.percent /100 * this.amount;
}

}

This returns undefined

Answer 1

Your loan function calling has 2 arguments passing but defination has 3 arguments without defaults...... Same with calc Year Income.
And loan function has not returning anything... Return a value.....
