I was making a sphere using three.js but the output is just a black screen as shown.
The code I used is:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>My first three.js app</title>
<style>
body { margin: 0; }
</style>
</head>
<body>
<script src=""></script>
<script>
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera( 75, window.innerWidth / window.innerHeight, 0.1, 1000 );
const renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );
const geometry = new THREE.SphereGeometry( 15, 32, 16 );
const material = new THREE.MeshBasicMaterial( { color: 0xffff00 } );
const sphere = new THREE.Mesh( geometry, material );
scene.add( sphere );
camera.position.z = 5;
function animate() {
requestAnimationFrame( animate );
sphere.rotation.x += 0.01;
sphere.rotation.y += 0.01;
renderer.render( scene, camera );
};
animate();
</script>
</body>
</html>
I couldn't explain why the code was unable to render the sphere. What went wrong?

Your camera is inside the sphere. Move it a bit further away from the origin like in the following live example:
const scene = new THREE.Scene();
const camera = new THREE.PerspectiveCamera(75, window.innerWidth / window.innerHeight, 0.1, 1000);
camera.position.z = 50;
const renderer = new THREE.WebGLRenderer();
renderer.setSize(window.innerWidth, window.innerHeight);
document.body.appendChild(renderer.domElement);
const geometry = new THREE.SphereGeometry(15, 32, 16);
const material = new THREE.MeshBasicMaterial({
color: 0xffff00
});
const sphere = new THREE.Mesh(geometry, material);
scene.add(sphere);
function animate() {
requestAnimationFrame(animate);
sphere.rotation.x += 0.01;
sphere.rotation.y += 0.01;
renderer.render(scene, camera);
};
animate();body {
margin: 0;
