🌟 Why This Release Matters

This release establishes YpsilonEventHandler as the definitive solution for enterprise-grade event delegation. The combination of AbortController support and smart target resolution solves two of the most common pain points in modern web development:

  1. Memory leak prevention with efficient event cleanup
  2. Nested element handling for complex UI components

🚀 Get Started

npm install ypsilon-event-handler@1.6.4
<script src="https://cdn.jsdelivr.net/npm/ypsilon-event-handler@1.6.4/ypsilon-event-handler.min.js"></script>
class MyHandler extends YpsilonEventHandler {
  constructor() {
    super({
      'body': ['click']
    }, {}, {
      abortController: true,        // Modern cleanup
      autoTargetResolution: true,   // Handle nested elements
      enableStats: true             // Performance tracking
    });
  }
}

new MyHandler(); // Revolutionary event handling activated!
