Planning Your Project
Concept
Planning Your Project
Before writing code, sketch what your project does, what data it needs, and which functions you will build.
Spending ten minutes planning on paper, or in comments, before touching real code usually saves far more than ten minutes of confused rewriting later.
- Explain the core idea behind Planning Your Project.
- Predict output before running a change.
- Test one realistic and one unusual input.
- Use the result to make the next decision.
- 1. Read one concept.
- 2. Change the example.
- 3. Run, compare, and explain.
- 4. Complete the challenge below.
Self-check before continuing
Without looking at the example, describe what changes when you modify one input in Planning Your Project. Then reopen the editor and prove your explanation with a small test.
You are ready to continue when you can predict, test, and explain the result.
Your turn
Write your own project plan as comments for a small app of your choice.
Ask about this lesson or your next move. The guide explains the path without taking the work away from you.
