split the mesh apart and consolidate all faces into a single list

I am facing a challenge with my code where I need to explode a mesh loaded from the THREE.JSONLoader in order to gather all component faces into one list. However, every time I attempt to utilize the explode modifier, an error is thrown.

The ERROR message states: "THREE.ExplodeModifier is not a constructor"

Being new to JS, I have been trying to understand what exactly this error signifies but I'm still unsure of how I might be misusing THREE.ExplodeModifier.

I referenced the code snippet from this example.

    //loading site
    var siteLoader = new THREE.JSONLoader();
    var siteMesh = null;
    siteLoader.load(
     'https://api.myjson.com/bins/zduan',
     function ( geometry, materials ) {
       var material = new THREE.MeshBasicMaterial( { color: 0xff0000, wireframe: true, transparent: true } );
       siteMesh = new THREE.Mesh(geometry,material);
       scene.add(siteMesh);
       renderer.render(scene,camera);
     }
    );
    //exploding site

    function explodeSite(){
      if(siteMesh !== null){
        var explodeModifier = new THREE.ExplodeModifier();
        explodeModifier.modify(siteMesh);
        var numFaces = siteMesh.faces.length;
      }
    }

THREE.ExplodeModifier is a custom modifier that is not included in the main three.js library. In order to use it, you must manually add the ExplodeModifier.js file to your project. As shown in the example you provided:

<script src="js/modifiers/ExplodeModifier.js"></script>
