The pool component allows for object pooling. This gives us a reusable pool of entities to avoid creating and destroying the same kind of entities in dynamic scenes. Object pooling helps reduce GC pauses.
For example, we may have a game with enemy entities that we want to reuse.
<a-scene pool__enemy="mixin: enemy; size : 10"></a-scene>
var el = sceneEl.components.pool__enemy.requestEntity();
|Grow the pool automatically if more entities are requested after reaching the
|Mixin used to initialize the entities of the pool.
|Number of preallocated entities in the pool.
Request one of the available entities in the pool.
Relinquish an entity back to the pool.
