Neato. Here's same thing in a React component.

import React, { useState, useEffect } from "react";

export const RotatingGlobe = (props: { className?: string }) => {
  const globeEmojis = ["🌎", "🌍", "🌏"];
  const [currentGlobe, setCurrentGlobe] = useState(globeEmojis[0]);

  useEffect(() => {
    let i = 0;
    const interval = setInterval(() => {
      setCurrentGlobe(globeEmojis[i++ % globeEmojis.length]);
    }, 1000);

    return () => clearInterval(interval); // Cleanup interval on unmount
  }, []);

  return <div className={`${props.className}`}>{currentGlobe}</div>;
};
