Pure implementation of WeekendStatus

WeekendStatus.js

import * as React from 'react';

const WeekendStatus = ({ currentTime }) => {
  // Because we take currentTime as a prop, we now no longer depend
  // on the external system time in our render function. We are now
  // a pure function
  const dayOfWeek = new Date(currentTime).getDay();
  const isWeekend = [0, 6].includes(dayOfWeek);
  if (isWeekend) {
    return <p>It&apos;s the weekend!</p>;
  }
  return <p>It is not the weekend. :(</p>;
};

export default WeekendStatus;
