Code Review Comments

I love learning about technology and sharing that with others
Motivation
- These are the comments received to me during my code review and I really loved them since it will improve my understanding of the code :)
Comments Received During PR Review
- Use constants instead of String litterals to compare anything
- Use meaningful names of the variables
Add the comments before function declaration
- these comments are documenting comments
- documenting comments : describe the semantics of the class field and method
- Good documenting comments allows you to read and use that particular class or method without reading the implementation
Add the implementation comments on : internal working
- add them only necessary
