3.3 Summary and perception of learning content
3.3.1 learning content summary
learn many types of functions, need lots of consolidating, strengthening exercises. quality improvement.
2. Maintain a study of heart. Persevere. Let yourself to do better.
3. Practice exercises every day, consolidate if-else, branching structure, use function calls.
