Page Structure Variants

1. Standard Learn Page (Most Common)

---
title: Page Title
---

<Intro>
1-3 sentences introducing the concept. Use *italics* for new terms.
</Intro>

<YouWillLearn>

* Learning outcome 1
* Learning outcome 2
* Learning outcome 3-5

</YouWillLearn>

## Section Name {/*section-id*/}

Content with Sandpack examples, Pitfalls, Notes, DeepDives...

## Another Section {/*another-section*/}

More content...

<Recap>

* Summary point 1
* Summary point 2
* Summary points 3-9

</Recap>

<Challenges>

#### Challenge title {/*challenge-id*/}

Description...

<Hint>
Optional guidance (single paragraph)
</Hint>

<Sandpack>
{/* Starting code */}
</Sandpack>

<Solution>
Explanation...

<Sandpack>
{/* Fixed code */}
</Sandpack>
</Solution>

</Challenges>

2. Chapter Introduction Page

For pages that introduce a chapter (like describing-the-ui.md, managing-state.md):

<YouWillLearn isChapter={true}>

* [Sub-page title](/learn/sub-page-name) to learn...
* [Another page](/learn/another-page) to learn...

</YouWillLearn>

## Preview Section {/*section-id*/}

Preview description with mini Sandpack example

<LearnMore path="/learn/sub-page-name">

Read **[Page Title](/learn/sub-page-name)** to learn how to...

</LearnMore>

## What's next? {/*whats-next*/}

Head over to [First Page](/learn/first-page) to start reading this chapter page by page!

Important: Chapter intro pages do NOT include <Recap> or <Challenges> sections.

3. Tutorial Page

For step-by-step tutorials (like tutorial-tic-tac-toe.md):

<Intro>
Brief statement of what will be built
</Intro>

<Note>
Alternative learning path offered
</Note>

Table of contents (prose listing of major sections)

## Setup {/*setup*/}
...

## Main Content {/*main-content*/}
Progressive code building with ### subsections

No YouWillLearn, Recap, or Challenges

Ends with ordered list of "extra credit" improvements

4. Reference-Style Learn Page

For pages with heavy API documentation (like typescript.md):

<YouWillLearn>

* [Link to section](#section-anchor)
* [Link to another section](#another-section)

</YouWillLearn>

## Sections with ### subsections

## Further learning {/*further-learning*/}

No Recap or Challenges

Heading ID Conventions

All headings require IDs in {/*kebab-case*/} format:

## Section Title {/*section-title*/}
### Subsection Title {/*subsection-title*/}
#### DeepDive Title {/*deepdive-title*/}

ID Generation Rules:

• Lowercase everything
• Replace spaces with hyphens
• Remove apostrophes, quotes
• Remove or convert special chars (:, ?, !, ., parentheses)

Examples:

• "What's React?" → {/*whats-react*/}
• "Step 1: Create the context" → {/*step-1-create-the-context*/}
• "Conditional (ternary) operator (? :)" → {/*conditional-ternary-operator--*/}

Teaching Patterns

Problem-First Teaching

Show broken/problematic code BEFORE the solution:

1. Present problematic approach with // 🔴 Avoid: comment
2. Explain WHY it's wrong (don't just say it is)
3. Show the solution with // ✅ Good: comment
4. Invite experimentation

Progressive Complexity

Build understanding in layers:

1. Show simplest working version
2. Identify limitation or repetition
3. Introduce solution incrementally
4. Show complete solution
5. Invite experimentation: "Try changing..."

Numbered Step Patterns

For multi-step processes:

As section headings:

### Step 1: Action to take {/*step-1-action*/}
### Step 2: Next action {/*step-2-next-action*/}

As inline lists:

To implement this:
1. **Declare** `inputRef` with the `useRef` Hook.
2. **Pass it** as `<input ref={inputRef}>`.
3. **Read** the input DOM node from `inputRef.current`.

Interactive Invitations

After Sandpack examples, encourage experimentation:

• "Try changing X to Y. See how...?"
• "Try it in the sandbox above!"
• "Click each button separately:"
• "Have a guess!"
• "Verify that..."

Decision Questions

Help readers build intuition:

"When you're not sure whether some code should be in an Effect or in an event handler, ask yourself why this code needs to run."

Component Placement Order

1. <Intro> - First after frontmatter
2. <YouWillLearn> - After Intro (standard/chapter pages)
3. Body content with <Note>, <Pitfall>, <DeepDive> placed contextually
4. <Recap> - Before Challenges (standard pages only)
5. <Challenges> - End of page (standard pages only)

For component structure and syntax, invoke /docs-components.

Code Examples

For Sandpack file structure, naming conventions, code style, and pedagogical markers, invoke /docs-sandpack.

Cross-Referencing

When to Link

Link to /learn:

• Explaining concepts or mental models
• Teaching how things work together
• Tutorials and guides
• "Why" questions

Link to /reference:

• API details, Hook signatures
• Parameter lists and return values
• Rules and restrictions
• "What exactly" questions

Link Formats

[concept name](/learn/page-name)
[`useState`](/reference/react/useState)
[section link](/learn/page-name#section-id)
[MDN](https://developer.mozilla.org/...)

Section Dividers

Important: Learn pages typically do NOT use --- dividers. The heading hierarchy provides sufficient structure. Only consider dividers in exceptional cases like separating main content from meta/contribution sections.

Do's and Don'ts

Do:

• Use "you" to address the reader
• Show broken code before fixes
• Explain behavior before naming concepts
• Build concepts progressively
• Include interactive Sandpack examples
• Use established analogies consistently
• Place Pitfalls AFTER explaining concepts
• Invite experimentation with "Try..." phrases

Don't:

• Use "simple", "easy", "just", or time estimates
• Reference concepts not yet introduced
• Skip required components for page type
• Use passive voice without reason
• Place Pitfalls before teaching the concept
• Use --- dividers between sections
• Create unnecessary abstraction in examples
• Place consecutive Pitfalls or Notes without separating prose (combine or separate)

Critical Rules

1. All headings require IDs: ## Title {/*title-id*/}
2. Chapter intros use isChapter={true} and <LearnMore>
3. Tutorial pages omit YouWillLearn/Recap/Challenges
4. Problem-first teaching: Show broken → explain → fix
5. No consecutive Pitfalls/Notes: See /docs-components Callout Spacing Rules

For component patterns, invoke /docs-components. For Sandpack patterns, invoke /docs-sandpack.
