/*                                        While-Loop-Testing-&-Analysis 

The following code is part of an ongoing project building an alogorithim ! 
The below code has proved an important piece in working with loops & while loops primarily building a program
that enables the while loop to work with TWO targets as the array is updated on each iteration. This is an 
important component of this alogorithim!

The below code provides an insight into the project & MOST importantly how in Java-Script how we build programs
using for & while loops with if, else if & else statements to generate desired sequential output in the 
developers console. 

NOTE
Results from TEST-TWO & TEST-THREE were not succesful HOWEVER the provide the foundations & good building blocks
to proceed with PROJECT !

For-Loop-Recap | For Loop in Java-Script has three parts:
1 - Initiate value of a counter
2 - Logical Condition - evaluated before each iteration of the loop
3 - Update counter after each iteration

WHILE-LOOP-MECHANICS
- If condition is true EXECUTE expression (code block)

BREAK-STATEMENT
- Completely terminates the LOOP
CONTINUE-STATEMENT
- Exits the current iteration of the loop and continues to next iteration
