Practical Promises

In this workshop, we'll be covering how to use promises for asynchronous control flow by using them to log out poem stanzas.

Follow the exercises in exercise-one.js and exercise-two.js. Each exercise includes a description of its objective as well as an example of a solution using vanilla async callbacks. For each exercise, come up with an equivalent solution using promises.

Execute your code with: node exercise-one or node exercise-two followed by the name(s) of the problems you want to run. For example, node exercise-one a will run problem A.

We will be using the bluebird promise library, and you'll likely find its documentation helpful. Strictly speaking you do not need any methods besides those of native ES6 promises, but some of the Bluebird methods may result in more elegant code.

Once you think you've figured out a problem, you can confirm by changing the spec for that from xit to it and running npm test.
