怎么用fetch+async模拟jQuery.when

Question

单个fetch+async

(async() => {

  try {

    var response = await fetch(url);

    var data = await response.json();

    console.log(data);

  } catch (e) {

    console.log("Booo")

  }

})();

如何像$.when一样发起多个请求

  $.when(...reqArr).done(function (...data) {

  }  

类似

requestByFetch(urls)
