# Skill: Resource Curator for Concept Pages Use this skill to find, evaluate, add, and maintain high-quality external resources (articles, videos, courses) for concept documentation pages. This includes auditing existing resources for broken links and outdated content. ## When to Use - Adding resources to a new concept page - Refreshing resources on existing pages - Auditing for broken or outdated links - Reviewing community-contributed resources - Periodic link maintenance ## Resource Curation Methodology Follow these five phases for comprehensive resource curation. ### Phase 1: Audit Existing Resources Before adding new resources, audit what's already there: 1. **Check link accessibility** — Does each link return 200? 2. **Verify content accuracy** — Is the content still correct? 3. **Check publication dates** — Is it too old for the topic? 4. **Identify outdated content** — Does it use old syntax/patterns? 5. **Review descriptions** — Are they specific or generic? ### Phase 2: Identify Resource Gaps Compare current resources against targets: | Section | Target Count | Icon | |---------|--------------|------| | Reference | 2-4 MDN links | `book` | | Articles | 4-6 articles | `newspaper` | | Videos | 3-4 videos | `video` | | Courses | 1-3 (optional) | `graduation-cap` | | Books | 1-2 (optional) | `book` | Ask: - Are there enough resources for beginners AND advanced learners? - Is there visual content (diagrams, animations)? - Are official references (MDN) included? - Is there diversity in teaching styles? ### Phase 3: Find New Resources Search trusted sources using targeted queries: **For Articles:** ``` [concept] javascript tutorial site:javascript.info [concept] javascript explained site:freecodecamp.org [concept] javascript site:dev.to [concept] javascript deep dive site:2ality.com [concept] javascript guide site:css-tricks.com ``` **For Videos:** ``` YouTube: [concept] javascript explained YouTube: [concept] javascript tutorial YouTube: jsconf [concept] YouTube: [concept] javascript fireship YouTube: [concept] javascript web dev simplified ``` **For MDN:** ``` [concept] site:developer.mozilla.org [API name] MDN ``` ### Phase 4: Write Descriptions Every resource needs a specific, valuable description: **Formula:** ``` Sentence 1: What makes this resource unique OR what it specifically covers Sentence 2: Why reader should click (what they'll gain, who it's best for) ``` ### Phase 5: Format and Organize - Use correct Card syntax with proper icons - Order resources logically (foundational first, advanced later) - Ensure consistent formatting --- ## Trusted Sources ### Reference Sources (Priority Order) | Priority | Source | URL | Best For | |----------|--------|-----|----------| | 1 | MDN Web Docs | developer.mozilla.org | API docs, guides, compatibility | | 2 | ECMAScript Spec | tc39.es/ecma262 | Authoritative behavior | | 3 | Node.js Docs | nodejs.org/docs | Node-specific APIs | | 4 | Web.dev | web.dev | Performance, best practices | | 5 | Can I Use | caniuse.com | Browser compatibility | ### Article Sources (Priority Order) | Priority | Source | Why Trusted | |----------|--------|-------------| | 1 | javascript.info | Comprehensive, exercises, well-maintained | | 2 | MDN Guides | Official, accurate, regularly updated | | 3 | freeCodeCamp | Beginner-friendly, practical | | 4 | 2ality (Dr. Axel) | Deep technical dives, spec-focused | | 5 | CSS-Tricks | DOM, visual topics, well-written | | 6 | dev.to (Lydia Hallie) | Visual explanations, animations | | 7 | LogRocket Blog | Practical tutorials, real-world | | 8 | Smashing Magazine | In-depth, well-researched | | 9 | Digital Ocean | Clear tutorials, examples | | 10 | Kent C. Dodds | Testing, React, best practices | ### Video Creators (Priority Order) | Priority | Creator | Style | Best For | |----------|---------|-------|----------| | 1 | Fireship | Fast, modern, entertaining | Quick overviews, modern JS | | 2 | Web Dev Simplified | Clear, beginner-friendly | Beginners, fundamentals | | 3 | Fun Fun Function | Deep-dives, personality | Understanding "why" | | 4 | Traversy Media | Comprehensive crash courses | Full topic coverage | | 5 | JSConf/dotJS | Expert conference talks | Advanced, in-depth | | 6 | Academind | Thorough explanations | Complete understanding | | 7 | The Coding Train | Creative, visual | Visual learners | | 8 | Wes Bos | Practical, real-world | Applied learning | | 9 | The Net Ninja | Step-by-step tutorials | Following along | | 10 | Programming with Mosh | Professional, clear | Career-focused | ### Course Sources | Source | Type | Notes | |--------|------|-------| | javascript.info | Free | Comprehensive, exercises | | Piccalilli | Free | Well-written, modern | | freeCodeCamp | Free | Project-based | | Frontend Masters | Paid | Expert instructors | | Egghead.io | Paid | Short, focused lessons | | Udemy (top-rated) | Paid | Check reviews carefully | | Codecademy | Freemium | Interactive | --- ## Quality Criteria ### Must Have (Required) - [ ] **Link works** — Returns 200 (not 404, 301, 5xx) - [ ] **JavaScript-focused** — Not primarily about C#, Python, Java, etc. - [ ] **Technically accurate** — No factual errors or anti-patterns - [ ] **Accessible** — Free or has meaningful free preview ### Should Have (Preferred) - [ ] **Recent enough** — See publication date guidelines below - [ ] **Reputable source** — From trusted sources list or well-known creator - [ ] **Unique perspective** — Not duplicate of existing resources - [ ] **Appropriate depth** — Matches concept complexity - [ ] **Good engagement** — Positive comments, high views (for videos) ### Red Flags (Reject) | Red Flag | Why It Matters | |----------|----------------| | Uses `var` everywhere | Outdated for ES6+ topics | | Teaches anti-patterns | Harmful to learners | | Primarily other languages | Wrong focus | | Hard paywall (no preview) | Inaccessible | | Pre-2015 for modern topics | Likely outdated | | Low quality comments | Often indicates issues | | Factual errors | Spreads misinformation | | Clickbait title, thin content | Wastes reader time | --- ## Publication Date Guidelines | Topic Category | Minimum Year | Reasoning | |----------------|--------------|-----------| | **ES6+ Features** | 2015+ | ES6 released June 2015 | | **Promises** | 2015+ | Native Promises in ES6 | | **async/await** | 2017+ | ES2017 feature | | **ES Modules** | 2018+ | Stable browser support | | **Optional chaining (?.)** | 2020+ | ES2020 feature | | **Nullish coalescing (??)** | 2020+ | ES2020 feature | | **Top-level await** | 2022+ | ES2022 feature | | **Fundamentals** (closures, scope, this) | Any | Core concepts don't change | | **DOM manipulation** | 2018+ | Modern APIs preferred | | **Fetch API** | 2017+ | Widespread support | **Rule of thumb:** For time-sensitive topics, prefer content from the last 3-5 years. For fundamentals, older classic content is often excellent. --- ## Description Writing Guide ### The Formula ``` Sentence 1: What makes this resource unique OR what it specifically covers Sentence 2: Why reader should click (what they'll gain, who it's best for) ``` ### Good Examples ```markdown <Card title="JavaScript Visualized: Promises & Async/Await — Lydia Hallie" icon="newspaper" href="https://dev.to/lydiahallie/javascript-visualized-promises-async-await-5gke"> Animated GIFs showing the call stack, microtask queue, and event loop in action.

What's unique? | | "in-depth look at..." | Vague | What depth? What aspect? | ### Words and Phrases That Work | Good Phrase | Example | |-------------|---------| | "step-by-step walkthrough" | "Step-by-step walkthrough of building a Promise from scratch" | | "visual explanation" | "Visual explanation with animated diagrams" | | "deep dive into" | "Deep dive into V8's optimization strategies" | | "practical examples of" | "Practical examples of closures in React hooks" | | "the go-to reference for" | "The go-to reference for array method signatures" | | "finally makes X click" | "Finally makes prototype chains click" | | "perfect for beginners" | "Perfect for beginners new to async code" | | "covers X, Y, and Z" | "Covers creation, chaining, and error handling" | --- ## Link Audit Process ### Step 1: Check Each Link For each resource in the concept page: 1. **Click the link** — Does it load? 2. **Note the HTTP status:** | Status | Meaning | Action | |--------|---------|--------| | 200 | OK | Keep, continue to content check | | 301/302 | Redirect | Update to final URL | | 404 | Not Found | Remove or find replacement | | 403 | Forbidden | Check manually, may be geo-blocked | | 5xx | Server Error | Retry later, may be temporary | ### Step 2: Content Verification For each accessible link: 1. **Skim the content** — Is it still accurate? 2. **Check the date** — When was it published/updated? 3. **Verify JavaScript focus** — Is it primarily about JS? 4. **Look for red flags** — Anti-patterns, errors, outdated syntax ### Step 3: Description Review For each resource: 1. **Read current description** — Is it specific? 2. **Compare to actual content** — Does it match? 3. **Check for generic phrases** — "comprehensive guide", etc. 4. **Identify improvements** — How can it be more specific? ### Step 4: Gap Analysis After auditing all resources: 1. **Count by section** — Do we meet targets? 2. **Check diversity** — Beginner AND advanced? Visual AND text? 3. **Identify missing types** — No MDN? No videos? 4. **Note recommendations** — What should we add?
