082. looping lou: the power of repetition (ks3)
Discover the power of loops in programming. Learn how to use repetition to write efficient code and save time when building algorithms.
Imagine having to write "take a step" one hundred times just to make a character walk across the screen. That would be incredibly boring! Thankfully, programmers are wonderfully lazy. In this lesson, we will discover the power of repetition. You will learn how to use loops to tell the computer to repeat instructions automatically, making your code much faster and far more efficient.
