The Anatomy of Web Performance: Understanding Chunks and JavaScript Optimization

As web applications grow heavier, JavaScript bundle size directly impacts user experience through Time to Interactive (TTI) and CPU load on devices. This article explains how Angular's chunking strategy, lazy loading, and code splitting reduce initial payload, revealing the critical relationship between bundle optimization and real-world performance. Developers who master this trade-off can dramatically improve application responsiveness, especially on mobile devices and slower networks.
