reactjs-calculator-kata

Thin slice of a Calculator done via Inside-Out TDD. Uses React Hooks as well as EnzymeJS.

• UI done in ReactJS

Thin Slice: Add Operation

• note that at this juncture, it does not yet handle decimal addition (todo later)

To run:

• first, ensure you're using node 12 or better
  • You can use nvm to change node versions very easily with the npm use <nodversion>
• yarn - once, to initially install node-modules
• yarn start - should open a browser and run the calculator

To test: yarn test

Notes on Approach / Choices

• I chose to use JS Factories (classic JS Modules/Closure) instead of JS Classes for creating object instances for the functional core (domain) logic in src\domain
• went with an inside-out TDD approach vs. an outside-in approach
  • either way is fine, just figured we'd try inside-out this time
• tried out the Ava test framework this time instead of Jest, Mocha, etc
• Stuff I want to do later: Add TypeScript
