Throwing Darts

You've just recently been hired to calculate scores for a Dart Board game

Scoring Specs

• 0 points: radius above 10
• 5 points: radius between 5 and 10 inclusive
• 10 points: radius less than 5

Some specifications to follow

• An empty collection should return -1.
• If all radiuses are less than 5, award 100 BONUS POINTS!
• A collection of scores can be of any length.
• scores can be of any number between 1 and 20.

Write a function that accepts a collection of number values and returns a total score using the above specification.

Examples:

scoreThrows( [1, 5, 11] ) => returns 15
scoreThrows( [15, 20, 30] ) => returns 0
scoreThrows( [1, 2, 1, 4, 4, 2] ) => returns 160

Additional Requirements

• Write tests for your function using the Mocha and Chai Libraries.
  • Provide test for all cases. Handle unexpected inputs, invalid arguments, etc.
