this project you create an application that calculates the total cost of items selected from a lunch menu using a for loop and an if statement as part of the program code. The cost of each menu item is stored in the value attribute of an input control on a web form. Because attribute values are treated as text strings, you will have to convert the attribute value to a number using the following JavaScript function: below is js is incomplete. //Declare the variable for MenuItems //variable for menu let menuItems = document.getElementsByClassName("menuItems")[i]; for(let i = 0; i < menuItems.length; i++) { menuItems[i].addEventListener("click", calcTotal()); } //Function for calcTotal function calcTotal(){ let orderTotal = 0; for(i = 0; i < 5; i++) { if(menuItems[i].checked) { orderTotal += (Number(menuItems[0].value) * 1); } document.getElementById("billTotal").innerHTML = formatCurrency(orderTotal); } } // Function to display a numeric value as a text string in the format $##.## function formatCurrency(value) { return "$" + value.toFixed
