Add button functionality within a DOM in leaflet

I can't seem to figure this one out and I'm assuming that this is a problem of code intendation? I have a button that on click in Leaflet should change the basemap layer.

// Basemap Button - Left panel

L.Control.Watermark = L.Control.extend({
  onAdd: function(map) {
      var Basemap = L.DomUtil.create('img');

      Basemap.src = 'basemap.png';
      Basemap.style.width = '65px';
      Basemap.style.top = '-90px';
      Basemap.style.left = '10px';

      Basemap.addEventListener('click', function() {
        // Change the basemap layer of the map to the OpenStreetMap Street View layer
        var osmStreetViewLayer = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
          attribution: 'Map data &copy; <a href="https://www.openstreetmap.org/">OpenStreetMap</a> contributors'});

      return Basemap;
  },
});

L.control.watermark({ position: 'topleft' }).addTo(map);

The issue seems to be on closing "});" ?

Returns error on });

The revised code fixed the error, plus some further considerations to make the basemap toggle, in case someone tries a similar project:

// Basemap Button - Left panel

L.Control.Watermark = L.Control.extend({
  onAdd: function(map) {
    var Basemap = L.DomUtil.create('img');

    Basemap.src = 'basemap.png';
    Basemap.style.width = '65px';
    Basemap.style.top = '-40px';
    Basemap.style.left = '10px';
    Basemap.title = 'Change Basemap'; // Add this line to set the title attribute
    Basemap.addEventListener('click', function() {
      if (map.hasLayer(osmStreetViewLayer)) {
        // Remove the OpenStreetMap Street View layer and add back the original layer
        map.removeLayer(osmStreetViewLayer);
        map.addLayer(originalLayer);
      } else {
        // Remove the original layer and add the OpenStreetMap Street View layer
        map.removeLayer(originalLayer);
        osmStreetViewLayer.addTo(map);
      }
    });

    return Basemap;
  },
});

Where and how is this Laravel kernel constructor called? [closed]

Where and how is this Laravel kernel constructor called? public fucntion __construct(Application $app, $Router $roouter) { } I have read the documentation and some online tutorial but I can find any clear explanation. I am learning Laravel and I am wondering where does this kernel constructor receives its arguments from. "POSTMOTERM" CLARIFICATION: Here is more clarity.I have checked the boostrap/app.php and it is only used for boostrapping the interfaces into the container class. What is not clear to me is where and how the Kernel class is instatiated and the arguments passed to the object calling the constructor.Something similar to; obj = new kernel(arg1,arg2) or, is the framework using some magic functions somewhere? Special gratitude to those who burn their eyeballs and brain cells on this trivia before it goes into a full blown menopause alias "MARKED AS DUPLICATE". To some of the itchy-finger keyboard warriors, a.k.a The mods,because I believe in th...
