Patterns — Part 1
Spot and copy patterns. What comes next? This is part 1 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).
