First order of business is to describe the monster. We must know the enemy to defeat it. What is mutable state? Why is it useful? Is it a necessary evil or something we can dispense with altogether?

Next, we study it’s modus operandi. What does it do exactly that makes gentlefolk go insane? What effects does it produce in concurrency? Why does it make debugging and reasoning about our code harder?

After that, we will look at various tools that functional programming offers us that can aid our quest. Referential transaprency and Immutable data structures are our allies.

Finally, we look at performance impact and how we can use these techniques in Android.
