javascript file not working when linked from HTML

Question

so I feel(and hope) this is pretty simple. I am new to javascript and am trying to get this working. When I link to my external .js file from my html it does not function. H

I have similar problem. Below is a code in two files which generates only white empty page, no errors are reported executing code, what is the problem?

index.html file:

main.js file:

function init() {
    var scene = new THREE.Scene();

    var box = getBox(1, 1, 1);
    var plane = getPlane(4);

    box.position.y = box.geometry.parameters.height/2;
    plane.rotation.x = Math.PI/2;

    scene.add(box);
    scene.add(plane);

    var camera = new THREE.PerspectiveCamera(
        45,
        window.innerWidth/window.innerHeight,
        1,
        1000
    );

    camera.position.x = 1;
    camera.position.y = 2;
    camera.position.z = 5;

    camera.lookAt(new THREE.Vector3(0, 0, 0));

    var renderer = new THREE.WebGLRenderer();
    renderer.setSize(window.innerWidth, window.innerHeight);
    document.getElementById('webgl').appendChild(renderer.domElement);
    renderer.render(
        scene,
        camera 
    );
}

function getBox(w, h, d) {
    var geometry = new THREE.BoxGeometry(w, h, d);
    var material = new THREE.MeshBasicMaterial({
        color: 0x00ff00
    });
    var mesh = new THREE.Mesh(
        geometry,
        material 
    );

    return mesh;
}

function getPlane(size) {
    var geometry = new THREE.PlaneGeometry(size, size);
    var material = new THREE.MeshBasicMaterial({
        color: 0xff0000,
        side: THREE.DoubleSide
    });
    var mesh = new THREE.Mesh(
        geometry,
        material 
    );

    return mesh;
}

init();
