Why Performance Matters Today

Core Principles
Build performance into the design rather than retrofitting it. Start optimizing early in your development process.

Critical Render Path
Minimize render-blocking resources
-
Image Delivery
Use modern formats like WebP
-
Code Efficiency
Tree-shake unused code
-
Lazy Loading
Defer non-critical resources
Modern Optimization Techniques
1. Critical Path Optimization
Prioritize rendering the above-the-fold content first. Use async attributes for scripts and defer parsing of unneeded JavaScript.
// Example critical CSS inlining
2. Image Optimization
Compress and format images appropriately. Use srcset for responsive images and loading="lazy" attribute for deferred loading.
// WebP format with progressive JPG fallback
