Patterns — Part 11
Spot and copy patterns. What comes next? This is part 11 of 20.
What you'll learn
You will learn to spot repeating patterns in code and predict what comes next.
Steps
- 1Look at the code. Can you see a pattern? The output alternates: A, B, A, B.
- 2Patterns repeat in a predictable way. If the pattern continues, the next output would be A, then B again.
- 3Spotting patterns is a superpower in coding — when you see something repeat, you can use a loop to save time.
- 4Think of a pattern you see every day (like day/night or red/green traffic lights). Coding uses patterns the same way!
Key Terms
- Pattern
- Something that repeats in a predictable way (e.g. A, B, A, B).
- Repeat
