*
* @example
*
* ```js
* map.on('click', function(e) {
* alert(e.latlng);
* } );

*
* Leaflet deals with event listeners by reference, so if you want to add a listener and then remove it, define it as a function:
*
* ```js
* function onClick(e) { ... }
*
* map.on('click', onClick);
* map.off('click', onClick);
