Tests:

Class method
class TransformComponent { constructor(scaleX = 1.0, scaleY = 1.0, rotation = 0.0) { this.scaleX = scaleX; this.scaleY = scaleY; this.rotation = rotation; } scale(factor = 1.0) { this.scaleX *= factor; this.scaleY *= factor; } }; for(let i = 0; i < 10000; i++) { const transform = new TransformComponent(i, i, i); transform.scale(2.0); }
Factory manager
const components = new Map; const noop = () => {}; const componentsMethodCaller = (factory, methodName, ...values) => { const methods = components.get(factory); return (methods[methodName] || noop).apply(null, values); } const transformFactory = (scaleX = 1.0, scaleY = 1.0, rotation = 0.0) => { return { scaleX, scaleY, rotation, }; } components.set(transformFactory, { scale(component, factor = 1.0) { component.scaleX *= factor; component.scaleY *= factor; }, }); for(let i = 0; i < 10000; i++) { const transform = transformFactory(i, i, i); componentsMethodCaller(transformFactory, 'scale', 2.0); }
