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)

Answer 1

使用Promise.all
