Naming and Style

Naming and Style

In this lesson — part of Conventions — you'll learn naming and style in Scheme and why it matters in real work.

Why it matters

Refactoring improves code's design without changing behavior — safely, in small steps.

Key ideas

• Code smells
• Small, safe steps
• Tests as a safety net
• Rename, extract, inline

In practice

Here's the idea in pseudocode — the exact syntax varies by language:

// Scheme: extract a function
function taxFor(x) { ... }

Try it yourself

Exercise: Take a long Scheme function and extract two well-named helpers.

Recap

You now understand naming and style and can apply it in Scheme. Mark this lesson complete and continue to the next one.
