Coffeescript + Jasmine - Pair Programming Exercise

ppcoffee.md

(don't start this early! lol)

Goal

The goal of this exercise is to learn how to pair program effectively. This is also an exercise in test driven development. Lastly, this is a team building exercise! :D

Coffeescript is being chosen as a useful language most Student Developers aren't very familiar with yet (although it's totally okay if you are).

Environment Setup & Background

• Set up your environment using these instructions.
• Comelete this exercise using Coffeescript and the testing framework Jasmine. For a quick run-through of Coffeescript, try Learn X in Y Minutes - Coffeescript. To see how a project might look with Javascript vs Coffeescript, check out this Ember Tutorial that can toggle between both.
• To get Jasmine working, read more about file modules, that should help. You will need to use the node.js feature module.exports.

Exercise

Scrabble Score

Write a program that, given a word, computes the scrabble score for that word.

Letter Values

You'll need these:

Letter                           Value
A, E, I, O, U, L, N, R, S, T       1
D, G                               2
B, C, M, P                         3
F, H, V, W, Y                      4
K                                  5
J, X                               8
Q, Z                               10

Examples

"cabbage" should be scored as worth 14 points:

• 3 points for C
• 1 point for A, twice
• 3 points for B, twice
• 2 points for G
• 1 point for E

And to total:

• 3 + 2*1 + 2*3 + 2 + 1
• = 3 + 2 + 6 + 3
• = 5 + 9
• = 14

Extensions

• You can play a :double or a :triple letter.
• You can play a :double or a :triple word.
