Overview

Memory optimization improves application performance, stability, and reduces infrastructure costs. Efficient memory usage is critical for scalability.

When to Use

• High memory usage
• Memory leaks suspected
• Slow performance
• Out of memory crashes
• Scaling challenges

Quick Start

Minimal working example:

// Browser memory profiling

// Check memory usage
performance.memory: {
  jsHeapSizeLimit: 2190000000,    // Max available
  totalJSHeapSize: 1300000000,    // Total allocated
  usedJSHeapSize: 950000000       // Currently used
}

// React DevTools Profiler
- Open React DevTools → Profiler
- Record interaction
- See component renders and time
- Identify unnecessary renders

// Chrome DevTools
1. Open DevTools → Memory
2. Take heap snapshot
3. Compare before/after
4. Look for retained objects
5. Check retained sizes

// Node.js profiling
node --inspect app.js
// Open chrome://inspect
// ... (see reference guides for full implementation)
