Ternary Operator
The Ternary Operator: ? , is a conditional operator that provides a shortcut assignment operator based on whether a condition evaluates to true or false.
The same logic can be represented using if - else logic, but Ternary operator provides a more concise format when using conditional logic to determine the value assigned to a variable.
Example logic: Goal - determine value to be assigned to index
if someTest is true
then set index = 5
otherwise, index = 10
