+ Performance Benefits: +
    +
  • โœ… Faster Initial Load: Only lightweight placeholders load initially
    • +
  • โœ… Reduced Bundle Size: Heavy components split into separate chunks
    • +
  • โœ… Better UX: Instant visual feedback, components load on demand
    • +
  • โœ… Memory Efficient: Components only consume memory when needed
    • +
  • โœ… Network Optimized: Parallel loading of components as user interacts

+ How it works: +
    +
  1. 1. Page loads instantly with lightweight placeholder buttons
    2. +
  2. 2. User clicks a button to interact with a feature
    3. +
  3. 3. Heavy component starts loading in the background
    4. +
  4. 4. Loading state shows immediate feedback
    5. +
  5. 5. Full component renders when ready
    6. +
  6. 6. Subsequent interactions are instant (component cached)
