Iteration (Loops)

Objective

Students must use loops to process collections of data and repeat operations.

Evidence

Using loops for game objects:

• Ghost.js - Distance calculation loop for pathfinding
• GameLevelOutside.js - Array.from() and map() for processing collections
• Multiple levels - Iterating over game objects in updates and renders

Implementation Details

• for loops for traditional iteration
• forEach() for functional iteration over arrays
• map() for transforming array elements
• Loops iterate over game object collections
• Animation frames updated in loops

Key Concepts

• Loop types: for, while, forEach, map
• Array iteration patterns
• Loop control (break, continue)
• Nested loops for complex operations
