The identity of depName remains elusive

I am encountering an issue where depName is undefined. I am attempting to iterate through the array but can't seem to figure out what's causing the problem. My goal is to determine the most profitable department from the sales data provided.

var salesData = [
{department : 'hardware', sales : 4500, day : 'Monday'},
{department : 'outdoor', sales : 1500, day : 'Monday'},
{department : 'carpentry', sales : 5500, day : 'Monday'},
{department : 'hardware', sales : 7500, day : 'Tuesday'},
{department : 'outdoor', sales : 2505, day : 'Tuesday'},
{department : 'carpentry', sales : 1540, day : 'Tuesday'},
{department : 'hardware', sales : 1500, day : 'Wednesday'},
{department : 'outdoor', sales : 8507, day : 'Wednesday'},
{department : 'carpentry', sales : 8009, day : 'Wednesday'},
{department : 'hardware', sales : 12000, day : 'Thursday'},
{department : 'outdoor', sales : 18007, day : 'Thursday'},
{department : 'carpentry', sales : 6109, day : 'Thursday'},
{department : 'hardware', sales : 7005, day : 'Friday'},
{department : 'outdoor', sales : 12006, day : 'Friday'},
{department : 'carpentry', sales : 16109, day : 'Friday'},
 ];

var depMap = {};
function mostProfitableDepartment() {
for (var i = 0; i < depName.length; i++) {
  var currentDep = depName[i]
}
console.log(currentDep);
}
mostProfitableDepartment(salesData);
javascript

Answer №1

Make sure to include the department name when defining your function

function calculateMostProfitableDepartment(nameOfDepartment) {

Answer №2

Don't forget to include the parameter in your function called mostProfitableDepartment

// Ensure to add depName in the function parameters
function mostProfitableDepartment(depName) {
    for (var i = 0; i < depName.length; i++) {
        var currentDep = depName[i];
        console.log(currentDep); // This line should be inside the loop
    }

}
