Doodles I drew during meetings/calls

My code quality has improved a lot, one thing I learned since last 3 months of training at rtCamp is

If something works, we might believe that that is the way, only way to do it, but it is just only single way that worked at that time.

it may or may not work in future, even it may not be the right way to do things, we should always find multiple ways to do something and then choose one of them.

Always question can it be done better?
