// Question: https://stackoverflow.com/questions/60623418/is-there-any-programmatic-way-to-break-infinite-loop-in-nodejs

const example = () => {
  const infiniteLoopWithSignal = async controller => {
    let iteration = 0;
    while (true) {
      if(controller.isStopped) break;
      console.log("Iteration: ", iteration++);
      await new Promise(resolve => setTimeout(resolve, 1000));
    }
    console.log("Stopped!");
  };

  const controller = {
    isStopped: false
  };
  infiniteLoopWithSignal(controller);

  // mutate signal from outisde
  setTimeout(() => {
    controller.isStopped = true;
  }, Math.floor(Math.random() * 10000 + 5000));
};
