Boost Website Performance with Lazy Loading and Code Splitting: Smart Techniques for a Faster Web
## What is Lazy Loading?
Lazy loading is a technique that delays loading images or elements until they’re needed (in the viewport). It helps:
- Reduce initial page size
- Minimize HTTP requests
- Save bandwidth for users
---
## What is Code Splitting?
Code splitting divides large JavaScript files into smaller chunks that load only when required. This results in:
- Faster initial page load
- Better interactivity
- Lower perceived wait time
---
## How to Implement It?
- In HTML/JS:
- Use `loading="lazy"` on images and iframes
- In React/Next.js:
- Use `React.lazy()` or `dynamic import()` for components
- Use bundlers like Webpack or Vite to automate the process
---
## Additional Tips
- Test lazy loading on slow networks
- Use Lighthouse to monitor performance
- Avoid lazy loading critical elements (like logos or main banners)
