I'm trying to learn JavaScript. I'm working on a problem where I'm making a grocery list: an array of sub-arrays that contain item, quantity and price. From there I plan to add items, read back the list, remove items, etc. My current issue is I cannot access sub-methods. I can't seem to find documentation on how to do it - but I keep reading that these methods are private? So maybe I'm way off base. I can't figure out how else I could set this up so multiple methods all talk to each other.
var groceryList = function(food, quantity, price) {
this.item = {};
this.items = {food:food, quantity:quantity, price:price};
return this.items
this.addStuff = function(food, quantity, price) {
this.items.push({food:food, quantity:quantity, price:price});
return this.items
};
this.tallyList = function() {
return items.length;
}
}
var myList = new groceryList("cookie", 2, 1.00);
console.log(myList)
myList.addStuff("brownie", 1, 2.50);
console.log(myList.tallyList);
