Reference

We first looked at setDecisionComputer here.

Let’s get right into it.

actions/get-result.ts

interface Payload {
  computerDecision: {
    beats: string;
    value: string;
  };
  userDecision: string;
}

const getResult = (payload: Payload) => {
  const { computerDecision, userDecision } = payload;

  if (computerDecision.value === userDecision) {
    return {
      judgement: 'It’s a tie.',
      computer: 0,
      user: 0,
    };
  }

  if (computerDecision.beats === userDecision) {
    return {
      judgement: 'Computer wins…',
      computer: 1,
      user: 0,
    };
  }

  return {
    judgement: 'You win!!!',
    computer: 0,
    user: 1,
  };
};

export default getResult;

First we need to describe a typescript interface of expected types to be passed into this function. We need the computer decision and the user decision. The computer decision is a shape which contains the computer’s actual decision and what that decision beats. The user decision is the value the user chose.

The result returns an object made up of judgement, computer value and user value. The values are either 1 or zero depending on whether the user or computer won (a 1 is set) or lost (a 0 is set) whether there was a tie or one actor lost to the other.

And that’s it really.
