Routing with Express

This is an express application that performs statistical operations (mean, median and mode) given an arbitrary list of numbers. Each route will have an operation.

The numbers will be given as query parameters, and the app will check if there are errors in this query. The returned results will be in JSON format.

Example of good routes:
http://localhost:3000/mode?nums=1,3,5,6
http://localhost:3000/median?nums=1,3,5,6
http://localhost:3000/mean?nums=1,3,5,6

Example of bad route:
http://localhost:3000/mode?nums=1,3,5,foo
In this case, it will return an error
