 An Algorithm is one or more functions (or classes) that:

-* perform some internal calculations or data manipulations,
-* return one or more outputs,
-* have minimal side effects.

 Algorithms should be packaged in a way that would make it easy for readers to put them into larger programs.
 
 Algorithms should:
 
-* have intuitive class and function names that make their purpose clear to readers
-* use JavaScript naming conventions and intuitive variable names to ease comprehension
-* be flexible to take different input values
-* raise JavaScript exceptions (RangeError, etc.) on erroneous input values
