Creating Custom Events

How do you debug custom events effectively?

function debugEvents(eventName) {
  document.addEventListener(eventName, function(e) {
    console.group(`Event: ${eventName}`);
    console.log('Target:', e.target);
    console.log('Current Target:', e.currentTarget);
    console.log('Detail:', e.detail);
    console.log('Bubbles:', e.bubbles);
    console.log('Cancelable:', e.cancelable);
    console.trace('Event Stack');
    console.groupEnd();
  });
}

Use alert statements
Ignore debugging
Use console logging and browser tools
Effective custom event debugging involves: 1. Using browser developer tools: - Event listener breakpoints - Network tab for async operations - Performance profiling 2. Implementing logging strategies: - Console groups for related information - Stack traces for event flow - Detailed event property logging 3. Monitoring event flow: - Bubbling path - Event target identification - Handler execution order 4. Testing event behavior: - Event property validation - Handler execution verification - Error condition testing
Only check event names
