Well done! Loops are commonly used in programming because they save time, reduce error, and are easy to read. Being comfortable with each type of loop will make you a better programmer. In review:

• A loop is a structure in programming where the instructions are written once, but a computer can execute them multiple times
• Each execution of those instructions is called an iteration
• For loops (count-controlled loops) repeat for a specified number of times
• While loops (condition-controlled loops) repeat until a condition changes
• For each loops (collection-controlled loops) repeat for each item in a collection
