Tuples are another way of storing multiple values in a single value. They have a fixed number of elements (immutable), and so you can't cons to a tuple. Elements of a tuple do not need to be all of the same type!
Example usage:
var tuples = require('fantasy-tuples'),
Tuple2 = tuples.Tuple2;
Tuple2(1, 2)._1; // 1 Fantasy Options uses nodeunit for all the tests and because of this there is currently an existing adapter in the library to help with integration between nodeunit and Fantasy Check.
Currently Fantasy Check is using Istanbul for code coverage analysis; you can run the coverage via the following command:
This assumes that you have istanbul installed correctly.
istanbul cover nodeunit -- test/*.js
