Loops
Review

Great job! In this lesson, we learned how to write cleaner code with loops. You now know:

  • Loops perform repetitive actions so we don’t have to code that process manually every time.
  • How to write for loops with an iterator variable that increments or decrements
  • How to use a for loop to iterate through an array
  • A nested for loop is a loop inside another loop
  • while loops allow for different types of stopping conditions
  • Stopping conditions are crucial for avoiding infinite loops.
  • do...while loops run code at least once— only checking the stopping condition after the first execution
  • The break keyword allows programs to leave a loop during the execution of its block
