Calculate Tournament Results in JavaScript

This is a bonus assignment. Complete it at your own pace.

The 2016 and 2017 Houston Indoor Ultimate Tournaments were a roaring success! Teams from all over the state battled it out on an indoor field and much fun was had by all.

Darren the statistician wants to calculate metrics about how teams performed in order to analyze the upcoming club tournament season. The tournament director wants to see how all the teams performed in order to award trophies.

Conveniently, the tournament director stored the tournament data in JSON:

Assignment

Using higher-order functions (map, reduce, filter, etc), write a solution that generates the results needed and passes the test suite.

A skeleton for your functions has been started in calculate-results.js

Development Setup

Make sure Node.js is installed on your system. Then, on the command line:

# installs the node_modules folder (one-time step)
npm install

# runs the test suite
npm test

Result Object

Darren the statistician has requested the tournament results in the following format:

{
  "team5": {
    "gamesLost": 3,
    "gamesPlayed": 5,
    "gamesTied": 0,
    "gamesWon": 2,
    "place": 8,
    "pointDiff": -7,
    "pointsLost": 38,
    "pointsPlayed": 69,
    "pointsWon": 31,
    "teamCaptain": "Ryan Levins",
    "teamName": "Eggpants Parmesan",
    "victoryPoints": 5993
  },
   "team2": { /* team2 result object goes here */ },
   "team3": { /* team3 result object goes here */ }
   /* the rest of the teams go here */
}

The tournament director has requested the results in an Array sorted by victory points:

    "games-lost": 0,
    "games-played": 7,
    "games-tied": 0,
    "games-won": 7,
    "place": 1,

    "points-lost": 35,
    "points-played": 98,
    "points-won": 63,
    "team-captain": "Sean McCall",
    "team-id": "team6",
    "team-name": "No Tsu Oh",
    "victory-points": 21028
  },
  { /* second place team goes here */ },
  { /* third place team goes here */ }
  /* the rest of the teams go here */
]

teams in your results.
There were some games that were aborted for various reasons. Only include
games marked as "final" in your results.
