YpsilonEventHandler v1.8.2 Release Notes

Type: Minor Feature Release

🚀 Major New Features

Fluent Chaining API

Revolutionary new methods for chainable event operations:

• on(type, handler, target) - Chainable event registration
• subscribe(type, handler, target) - Semantic alias for event subscription
• emit(type, detail, target) - Chainable custom event dispatch

Example:

// Register multiple listeners and emit events in one statement
this.on('data-ready', 'handleData')
    .on('user-login', 'handleLogin')
    .subscribe('app-ready', 'handleAppReady')
    .emit('init-complete', { loaded: true, timestamp: Date.now() });

Enhanced Browser Compatibility

• findClosest() polyfill - IE11+ support for Element.closest()
• Cross-browser DOM traversal - Works on browsers from 2012+
• Static property caching - Improved passive support detection

📚 Documentation Revolution
