Variable scope?

Question

JavaScript

Hello everyone, tell me how you can use it further in the code, namely in switche and beyond

var _loaders = {};



        _loaders.loadCurrentObject = function (a) {

    _loaders.object = a;
    console.log(a);


    function init() {

        var scene = new THREE.Scene();

        var camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 0.1, 50000);

        scene.add(camera);


        var webGLRenderer = new THREE.WebGLRenderer();
        webGLRenderer.setClearColor(new THREE.Color(0xffffff, 1.0));
        webGLRenderer.setSize(window.innerWidth, window.innerHeight);
        webGLRenderer.shadowMapEnabled = true;


        camera.position.x = 5;
        camera.position.y = 5;
        camera.position.z = 5;
        camera.lookAt(scene.position);
        scene.add(camera);

        var orbitControls = new THREE.OrbitControls(camera);
        orbitControls.autoRotate = true;
        var clock = new THREE.Clock();


        var directionalLight = new THREE.DirectionalLight(0xffeedd);
        directionalLight.position.set(100, 100, 150);
        camera.add(directionalLight);


        document.getElementById("WebGL-output").appendChild(webGLRenderer.domElement);


        var step = 0;


        var mesh;


        switch (a.extension) {
            case 'obj':
                if (a.texture != "http://placehold.it/200x200") {
                    _loaders.loader = new THREE.OBJMTLLoader();
                    _loaders.loadObjMtl(_loaders.object);
                } else {
                    _loaders.loader = new THREE.OBJLoader();
                    _loaders.loadObj(_loaders.object);
                }
                break;
            case 'stl':
                _loaders.loader = new THREE.STLLoader();
                _loaders.loadStl(_loaders.object);
                break;
        }

        _loaders.loadObj = function (a) {
            _loaders.loader.load('/files/uploads/objects/'+ a.id + '/' + a.url, function (loadedMesh) {

                loadedMesh.children.forEach(function (child) {
                    child.material = material;
                    child.geometry.computeFaceNormals();
                    child.geometry.computeVertexNormals();
                });

                mesh = loadedMesh;
                loadedMesh.scale.set.x = 45;
                loadedMesh.scale.set.y = 45;
                loadedMesh.scale.set.z = 45;
                loadedMesh.rotation.x = -0.3;
                scene.add(loadedMesh);



            });
        };


        render();


        function render() {


            var delta = clock.getDelta();
            orbitControls.update(delta);

            requestAnimationFrame(render);
            webGLRenderer.render(scene, camera);

        }


    }

    window.onload = init;
     };

There was such a problem. It is necessary to pass directly in when declaring , and init(a)also pass before the call . Change the structure of the code a little. init() should preferably be declared asаinit()init()var init = function(a) {};
