Examining the Object property accessor behavior

Consider the following scenario

function invert(color) {
  var lookup = {
    black: 'white',
    white: 'black'
 }

repeat(a) -> [a]

Inspired by Haskell, I wanted to see if I could replicate, using ES6 features, the repeat function:

repeat :: a -> [a]

So as you can see in repeat.js, I have done exactly that. However there are some caveats.

Supercharge your git hooks with gulp

Introducing git-guppy

Automate your developer workflow with git-guppy. git-guppy allows you to add git-hooks to your project repository that are automatically installed when users clone and install your repository, so you won't have to worry about developers skipping essential workflow steps and bypassing your project guidelines.

Getting Started

So let's use a unit test scenario to illustrate an example. We're going to run unit tests before every commit (pre-commit hook) and reject the commit if the tests fail (giving the developer a chance to fix their tests before committing broken code).
