If you’ve developed games, you’ll probably know what ECS(Entity Component System) is, so I’m not going to elaborate its details. Instead, I’ll just use the following oversimplified pseudo-codes that trades optimizations for simplicity:

EntityManager { const createdEntity = components => { const entity = _createdEntity(); ComponentManager.attachAll(components, entity); return entity; }, destroy = entity => { ComponentManager.detachAll(entity); // Can become splice with the index found by binary search this._entities.= this._entities.filter(e => e !== entity); // // this._deletedEntities is ascendingly sorted so it’s impossible to already have entity this._deletedEntities.push(entity); this._deletedEntities.sort((a, b) => a - b); // This can be optimized into splice with the index found by binary search }, _createdEntity = () => { const deletedEntity_ = this._deletedEntities.shift(); // Reuses the deleted UUID to prevent any UUID being too large...
