/*
  - Map Data Type
  Syntax: new Map(Iterable With Key/Value)
  -- Map vs Object
  --
  ------ Map => Does Not Contain Key By Default
  ------ Object => Has Default Keys
  --
  ------ Map => Key Can Be Anything [Function, Object, Any Primitive Data Types]
  ------ Object => String Or Symbol
  --
  ------ Map => Ordered By Insertion
  ------ Object => Not 100% Till Now
  --
  ------ Map => Get Items By Size
  ------ Object => Need To Do Manually
  --
  ------ Map => Can Be Directly Iterated
  ------ Object => Not Directly And Need To Use Object.keys() And So On
  --
  ------ Map => Better Performance When Add Or Remove Data
  ------ Object => Low Performance When Comparing To Map
