Angular's Zoneless: Redefining Change Detection Performance

Angular's Zoneless architecture represents a fundamental shift from Zone.js's blanket change detection to Signal-driven fine-grained updates, directly addressing long-standing performance bottlenecks. By eliminating the Zone.js library's overhead (~13kb gzipped), applications achieve faster initialization and more predictable performance characteristics. Understanding this transition is critical for developers building high-performance Angular applications in an increasingly performance-conscious web environment.
