2. Your README is Your Sales Pitch: A clear README with quick-start examples isn't optional—it directly impacts downloads and adoption.
3. The Bundle Size Killer: How a large package size (over 50KB!) stops developers from installing. Key tips on using tree-shaking and optimization to keep your package small and efficient.
4. TypeScript Types Are Non-Negotiable: Why including .d.ts files is a must for modern development and IntelliSense. Don't make your TypeScript users angry!
