• Correctly implemented rules
  • http://en.wikipedia.org/wiki/Rock-paper-scissors

Technical Requirements

You should:

• Support multiple browsers
• Use vanilla JavaScript or Typescript (though please feel free to use additional libraries in solving the problem, based on your understanding of the role requirements)

• Use only ES2015+ syntax
• Use Semantic HTML

You should not:

• Submit a solution with compilation/runtime errors

Guidelines

Solution Design

Your solution should be clear and easy to understand, consider using popular software principles such as DRY, KISS, SOLID etc.

Try to avoid unnecessary complexity and over-engineering.

User Interface

The user interface can be as simple or as complex as you wish, however, you will be marked on:

• Responsive Design
• Accessibility

You will not be marked on your design choices.

Extensibility

Your solution should be easily extendable to include additional rules.

For example: http://en.wikipedia.org/wiki/Rock-paper-scissors-lizard-Spock

We provide the following tooling:

• webpack to modularise your Javascript code
• babel to utilise ES2015+ features
• node-sass to modularise your styling via SASS
• eslint to make sure your code meets the standards
• jest to help you write and run your unit tests
