+# JavaScript ES2015 solutions to Cracking the Coding Interview
+These are solutions and associated unit tests for the questions in Cracking the
+Coding Interview 6th edition using JavaScript ES2015 features. These solutions
+specifically take advantage of ES2015 enhancements to the JavaScript language
+and require the latest Node.js (>= v5.0.0) to work properly. As not all ES2015
+features are available in V8 yet babel is being used to fill in the gaps (at
+this point only the ES2015 module syntax is being transpiled by babel).
+
+### Setup the project
+Once downloaded ensure that Node.js is installed and run the following commands
+in this directory:
+```bash
+npm install
+```
+
+### Running unit tests
+The solutions are demonstrated by a set of unit tests which use the Mocha unit
+test framework and Chai as an assertions library. These tests can be executed
+at any time with:
+```bash
+npm test
+```
+
+As part of the unit tests ESLint will also be run against all files to ensure
+that the JavaScript is valid and follows best practice.
+
+### Linting source code
+While executing ESLint by itself is not necessary (as it runs as part of the
+unit test execution) you can choose to run it with:
+```bash
+npm run lint
+```
+
+### Dependencies
+This implementation of the solutions requires the following dependencies:
+
+* Node.js >= v5.0.0
+* npm >= v3
+* Mocha (installed via npm)
+* Chai (installed via npm)
+* Babel (installed via npm)
