There are two problems provided, arithmatic-problem-solver and power-problem-solver. Each project is found in their respective directories under /lib.

The arithmatic-problem-solver is compulsory, however the power-problem-solver is optional.

This project has several dependencies that must be installed before beginning, which include:

• Node.js
• NPM
• Mocha.js
• Istanbul

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine. It ships with an HTTP server framework for building highly scaleable web APIs. It is the platform on which this project is designed to run. To install visit the Download Node.js page, and download/install the latest LTS version.

Node.js was originally built to run on -nix baed systems. If you're running Windows, that's fine, but we recommend setting up a Linux virtual machine, and using your editor of choice (such as Atom or Sublime Text)) — it will make your life easier.

You can validate your install by running (from the Terminal):

$ node -v

NPM is the Node.js Package Manager. This utility should have installed with Node.js. You can validate its installation by running:

$ npm -v

If NPM is not installed, the easiest way to remedy the problem is to use a package manager, such as, Homebrew (on macOS), Apt (on Debian distributions), Yum (on CentOS distributions), or Chocolatey (on Windows).

Mocha.js is a test running for Node.js. You will need to install this package globally to take advantage of the unit tests we've provided for you.

$ sudo npm install -g mocha

Istanbul is a code coverage utility, and provides insights on code paths that may not be covered by unit tests. This utility, like Mocha.js, must be installed globally.

$ sudo npm install -g istanbul

Finally, you'll need to install the remainder of the project's dependencies. To begin cd into the project directory, and tell NPM to install all of the project's dependencies (as sepcified in package.json).

$ npm install

If at any time you get stuck, have questions about requirements, or have issues installing the prerequisites, please do not hesitate to reach out. Ultimately, Polis want you to succeed. If you have any questions, you can contact me any time via email at [email protected]. Cheers,
