Discussion
Should we include holidays like:
Halloween, April Fools Day, etc.

Future

• Include International holidays and/or localize

Add a screenshot of the current app to README or add a graphic that represents the website to the README.

Description
Pulled down the project to check it out and noticed that there were ~195 ESLint errors. Add a linting script and fix the existing ESLint errors.

Update dateHelper.js to eliminate this error.

run npm lint to view these errors locally

These are related to Flow which is a static type checker https://flow.org/

Current Repo README.md is the stock from create-react-app and does not describe the project at all

Add functionality to allow users to manually add a date to countdown from.

   17:7  error  'forkMe' is assigned a value but never used  no-unused-vars

Verify issue locally by running npm run lint. When it is resolved the error should no longer appear when you run npm run lint

Display the current date (and in the future this should be updated to display date that the countdown is referencing from).

Add information about Jodatime to the README. We use Jodatime instead of the native JavaScript Date object. What are the benefits? Are there any gotchas to be concerned about?

Potential sources for information:

Add website title "How Many Days Until"

HTML titles

defines a title in the browser tab
provides a title for the page when it is added to favorites
displays a title for the page in search engine results

In this PR #27 a Christmas countdown component was added. We need to add the ability to switch pages/vies this can be achieved by:

• giving Christmas a seperate route and linking to that route
• setting state that determines if Christmas or New Year's countdown should be displayed. It can default to New Year's countdown. This is the more React way imo.

• Any ideas for how this website can look better?

I like how https://hacktoberfest.lingonsaft.com/ if that's any inspiration.

Multiple people are welcome to work on this and open issues :)

Create new README

• include project name
• instructions for running application (borrowed from current README)

Rename/move current README.md to CHEATSHEET.md (link to CHEATSHEET in new README).

Encourage more contributions by adding a "Fork Me on GitHub" Banner. https://blog.github.com/2008-12-19-github-ribbons/

A CSS improvement (#23) that can be made is updating the Fork me banner on the current site to use https://github.com/tholman/github-corners

in order to resolve this error
