In this article I will take a very simplistic approach in understanding memory leaks and I will also attempt to diagnose them.
In todays world of abundant memory, we seldom worry about memory leakages. But I hate to tell you that we live in a real world and nothing comes for free.
Disclosure: I absolutely love functional programming. Functional programming is cool and with the new ES6 syntax it becomes even cooler.
