Looking good! Just need to make changes to index.js and add a test file here 😄

[kentcdodds]

I noticed that you added the test file in another pull request. Could you update this pull request to have all the changes necessary?

[jsina]

@kentcdodds there is no "npm run cover | npm run build' on travis.yml file. there is just 'npm prune' file under script title on that file

[kentcdodds]

If you look at the other implementations, you'll see that they also change the src/index.js file. Could you do the same for this one?

Wonderful! Thanks!
