await async 中如何做到并行处理？

例如：

function  getName(name){
  return Promise(function(){
    resolve(name + '123');
  });
}
(async ()=>{
var res = [];
for(const name of names){
   res[name] = await getName(name);
}
})();

可以await一个promise.all

pmap(array, async item => {
  // ...
}, concurrency)

function getName(name) { return new Promise(function(resolve, reject) { resolve(name + ‘123’); }); }

// jshint ignore: start (async function(names) { let res = await Promise.all(names.map(item => getName(item))); console.log(res); })([‘a’, ‘b’, ‘c’]); // jshint ignore: end
