Title Body

I have the following test code that is being ran by jasmine-node in a file called bob_test.spec.js require('./bob'); describe("Bob", function() { var bob = new Bob(); it("stating something", function() { var result = bob.hey('Tom-ay-to, tom-aaaah-to.'); expect(result).toEqual('Whatever'); }); }); In order to make the test pass, I've written the following production code in a file called bob.js "use strict"; var Bob = function() { } Bob.prototype.hey = function (text) { return "Whatever"; } module.exports = Bob; When I run the test - using jasmine-node . - I get the following F Failures: 1) Bob encountered a declaration exception Message: ReferenceError: Bob is not defined Stacktrace: ReferenceError: Bob is not defined at null.<anonymous> (/Users/matt/Code/oss/deliberate-practice/exercism/javascript/bob/bob_test.spec.js:4:17) at Object.<anonymous> (/Users/matt/Code/oss/deliberate-practice/exercism/javascript/bob/bob_test.spec.js:3:1) at Module._compile (module.js:456:26) at Object.Module._extensions..js (module.js:474:10) at Module.load (module.js:356:32) at Function.Module._load (module.js:312:12) at Module.require (module.js:364:17) at require (module.js:380:17) Finished in 0.02 seconds 1 test, 1 assertion, 1 failure, 0 skipped Based on what I understand about Javascript, I feel like this should work. What does node.js do differently with constructor functions and module exports that prevents this from working I like think it should?
