Pros and Cons of Garbage Collector

Pros.
------------------
- it helps to recollect out of scope/session objects and reclaims memory.
- improves application performance by improving memory.

Cons.
-----------------
- its a heavy process to reclaim memory.

NOTE: for best programming practices, programming should be done in a way that program itself manages object to reclaim and out of scope objects created in minimal, so as creating minimum load on GC.
