A learner may encounter variables, conditions, methods, and classes without seeing how these ideas relate. Short code samples can look understandable in isolation while remaining difficult to adapt to a fresh task.

Repeated instructions, unclear relationships between objects, and poorly organized data can make even relatively small applications challenging to maintain. Learners may understand individual programming concepts while remaining uncertain about how to arrange them within a connected application.
