simple promise queue framework

promise queue

export const PromiseQueue = function() {
  let defered = Promise.resolve();

  return {
    push(fn) {
      defered = defered.then(fn, fn);
      return this;
    }
  };
};

export const waitOnQueue = function(fn, time = 100) {
  return function() {
    return new Promise((resolve, reject) => {
      setTimeout(() => {
        requestAnimationFrame(() => {
          fn();
          resolve();
        });
      }, time);
    });
  };
};
