Baby stepped implementation of reverse polish notation for a kata.

Reverse Polish Notation

https://en.wikipedia.org/wiki/Reverse_Polish_notation

The input for the function should be a space separated string.

End Goal Test

1 2 + 4 * 5 + 3 - = 14

However feel free to take it as far as you like.

See it done or do it yourself?

You can watch me implement this at 12x speed: https://youtu.be/UL0jsN4uPow
If you'd like to do this kata yourself checkout the master branch

Baby step rules

1. Start a timer (3 minutes suggested but whatever you're comfortable with)
2. Write exactly 1 test
   • If the timer ends and the test is red then git reset --hard
   • If the test is green then git commit -a -m "refactor {feature}"
3. Restart timer
4. Refactor
   • If the timer ends and refactoring is not complete then git reset --hard
   • If the refactoring is complete before the timer ends git commit -a -m "refactor {feature}"
5. Goto 1 goto statements ftw

Additional Challenges

• Smallest steps - Create the most tests (must show forward progress of code between commits).
• ES6 - Use the most ES6 features.

Setup/Running Tests

Install dependencies

npm install

Run tests

npm test

The test framework is Mocha and the assertion library is Should feel free to set something else up if you're more comfortable with it, this has just been provided for your convenience.
