// 1) Create a for loop that loops through its code block 10 times
// In the first statement, set the variable i equal to zero
// In the second statement, tell the loop to execute while i is less than ten
// In the third statement, increment i by one each time the loop executes
// In the code block of the loop, print the variable i to the console



// 2) Create an array named foods and put your 5 favorite foods
// in the array as items.
// 5 fav foods = sushi, ramen, korean bbq, pizza, wings
// Create a for / in loop that will loop through the items in the foods array
// Print a favorite food item to the console each time the loop executes
// When finished, you should have printed each favorite food item to the console



// 3) Create a variable x and set it equal to 50.
// Create a while loop that executes while x is greater than zero.
// Print the value of x to the console every time the loop executes.
// Decrement the value of x by one every time the loop executes.
// Your loop should count backwards from 50 to 1 and print each number in the
// console.



// 4) Create a variable named myNum and set it equal to 10.
// Create a while loop that executes while myNum is less than 5.
// In the loop, print the value of myNum to the console.
// Below that loop, create a do / while loop.
// Set the while condition the same as first while loop.
// Print the value of myNum to the console in the loop.
// Comment below your loops to explain the outcome. /* multi-line comment */



// 5) Create a variable named x and set it equal to zero.
// Create a while loop that executes while x is less than ten.
// In the code block of the loop, set x equal to a random number between
// one and ten using the previous random number formula we learned with
// the Math object.
// After assigning x the random number, print the value of x to the console.
// The loop should continue to execute until the value of x equals 10.
