* When it is necessary to work with a large number of objects that are particularly expensive to instantiate

|

* The object pool design pattern creates a set of objects that may be reused. When a new object is needed, it
|
||||
* is requested from the pool. If a previously prepared object is available it is returned immediately, avoiding
|
||||
* the instantiation cost. If no objects are present in the pool, a new item is created and returned. When the
|
||||
* object has been used and is no longer needed, it is returned to the pool, allowing it to be used again in the
|
||||
* future without repeating the computationally expensive instantiation process. It is important to note that
|
||||
* once an object has been used and returned, existing references will become invalid.
