• Our 2 Loop Types

• For Loop

• Do-While Loop

• I know in advance how many loops to do

• Loop until a condition is met

• for (var i=0; i<24; i++){
• do some code
• }

• do {
• do some code
• }
• while (usedNums[newNum]);

• Start at 0 and loop 24 times (why 24?)

• Loop until you have a unused number
