Usage

To use Witch JS, simply call the witch() function with the element selector as the argument. Then, chain the event you want to handle using the on() method, passing in the event type and the handler function.

  alert('Button clicked!');
});

// Add event handler
myBtn.on('click', myClickHandler);
