const createQueue = () => {
  let queue = Promise.resolve();
  return <T extends () => any>(task: T) => {
    queue = queue.then(() => task());
  };
};

const queue = createQueue();

// example

const delay = (ms: number) => {
  new Promise((resolve) => {
    setTimeout(resolve, ms);
  });
};
    
queue(() => delay(1000).then(() => console.log('1')));
queue(() => delay(100).then(() => console.log('2')));
queue(() => console.log('3'));
// output: 1, 2, 3
