// Comments
//-------------------------------

/*
  This is a multi-line comment
  (you probably shouldn't use these).
  Use CMD + / or CTRL + / on your editor.
  (if your editor doesn't have a way to do this,
  throw it away.)

// Variables
//-------------------------------
 
// The first time you use a variable, you need to prefix it with var.

// after that you can just use it.
first = 'FIRST VARIABLE';

// console.log('VALUE OF THIRD', third);
 
 
// Strings
//-------------------------------
 
 
// Double quotes and single quotes are the same
 
// Except that you need to escape a single quote inside a single quoted string
'Nizar\'s Pizza'
'Nizar likes "coding"'
 
// You need to escape a double quote inside a double quoted string
"Nizar's Pizza"
"Nizar likes \"coding\""
 
// That means that there is no string interpolation #{} in JavaScript.
// You need to stitch together your strings with +
"Nizar" + " other string " + "etc"
 
 
 
// Comparisons
//-------------------------------
 
// Use === because...
console.log(0 == '0');
console.log(0 == '');
console.log('0' == '');
 
// WAT
// == transforms the type of one to match the other and then compares

//-------------------------------

// for ([1]; [2] [5]+; [4] [7]+)
// {
//   [3] [6]+
// }
//
// [8]
 
// First section of for is the starting point
// Second section is the condition (just like in a while loop)
// Third section is to change the variable in the condition

//-------------------------------

function printFoodsOrWhatever (item) {
    console.log(item);

// Objects (a.k.a. hashes)
//-------------------------------
 
var obj = {
