git clone
npm install       # install all modules
npm test          # single run of tests
npm watch:test    # watch tests on file changes

some additional learnings

1. create grouped-katas-spec.js to see if test setup is working at all
2. exclude node_modules for faster indexing
3. have a look at uncle bob -> clean code
4. add ./node_modules/.bin to PATH
5. use babel src/grouped-katas.js to see what gets generated
6. opinion: have tests in same directory as source to get rid of ../../../src/some/where/source.js imports
7. renderer = TestUtils.createRenderer() and renderer.getRenderOutput() to check virtual dom

Question

1. transform via babel or browserify (reactify)? -> reactify makes sense for consistency (using babelify+reactify)
