Lazy loading is one of the most popular frontend optimizations today. The concept is simple: don’t load it until it’s needed.
The Good Parts
Faster initial load
Less data usage
Better perceived speed
Great for images, routes, and heavy components
The Risky Side
It can delay interactivity when users scroll quickly
It may cover up poor architecture decisions
If your bundles are massive, you're delaying pain, not removing it
Without placeholders, users feel the delay
The Balanced View
Lazy loading is not the solution — it's a tool.
When used with:
Proper code-splitting
Optimized images
Preload for critical assets
Stable UI placeholders
Real user performance monitoring
…it becomes a performance champion 🏆
When used alone to justify shipping heavy code?
…it’s just a ticking timer ⏳
