A really useful function, or Jessica learns about object prototypes

alternatelord.js

var food = function(type) {

  function changeType(newType) {
    type = newType
  }
  
  function judgment() { 
    if (type === "bread" || type === "olives") {
      return "Awesome tastes"
    } else {
      return "Sucky crappy tastes, man"
    }
  }
  
  return {
    changeType: changeType,
    judgment: judgment
  }
  
}

var bread = food('bread')
console.log(bread.judgment())
bread.changeType('taco')
console.log(bread.judgment())

javalord.js

function Food(type) {
  this.foodType = type

  } else {

  }
}

Food.prototype.changeType = function(newType) {
  this.foodType = newType

var bread = new Food("bread")
var cheese = new Food("mozz")

console.log(bread.judgement())
bread.changeType("Pizza")
console.log(bread.judgement())
