# JavaScript instance creation [Back to Scene, instances, cameras, and input](https://rustic-game-engine.pages.dev/markdown/scripting/javascript/scene-instances-cameras-and-input.md). Use these calls inside a JavaScript lifecycle callback. ```javascript instance.add("Cube"); const camera = Game.scene.Find("Room.Camera"); instance.clone("assets/models/chair.obj", camera); ``` An instance source can be a stable ID, scene path, model path, or built-in object name. Instance calls queue creation and do not return the new ID. A parent, when supplied, must be a stable ID.
