Performance difference between query.Each() and component.Each()

[setanarut]

Is there a performance difference between query.Each() and component.Each() for a single component? Do I need to use a *donburi.Query variable for a single component?

// Query all Bullet entities
Bullet.Each(world, func(entry *donburi.Entry) {
  bullet := Bullet.Get(entry)
  // .. do stuff with the bullet entity
})

Or

// Define a query by declaring what componet you want to find.
query := donburi.NewQuery(filter.Contains(Bullet))

// Iterate through the entities found in the world
query.Each(world, func(entry *donburi.Entry) {
  // An entry is an accessor to entity and its components.
  bullet := Bullet.Get(entry)
})

Also, Is it better to use PlayerEntry.Valid() in every update frame or *donburi.Query.First() query?

Hello, both of them are the same operation internally so there's no difference between them.
