A simple sorting problem with a story
The FBI is hot on the trail of a notorious, international smuggler who has fled the jurisdiction. Fortunately, your office has discovered a stack of train tickets that your quarry has foolishly abandoned on his escape. You can use these to track your target. Unfortunately, the tickets are out of order, and they must be sorted before any action can be taken. You, being a resourceful and technically savvy agent, offer to write a quick Node.js application that takes in the randomly sequenced array of ticket-objects and returns the array of tickets sorted. Each ticket contains two fields ({from: string, to: string}), which you will use to sort them, mapping the smuggler's path.
This repository provides you with a node app and some starter code in index.js. Use it, and complete the sort_tickets() function, ordering the tickets such that the to property in the initial ticket is the same as the from property of the next sequential ticket, and so on.
Once the tickets are sorted, log the final city to the console to reveal the whereabouts of the suspect.
Because you're a careful agent, you will write one or more tests in tests\case_cracker.test.js file to verify the proper function of your code.
Good luck, and be careful!
