Suppose I am getting 05:30 from the frontend and I need to add to the current UTC time. How can I do that using momentjs?
I tried that but didn't work

我正在获得对象的数组,并且在那些对象中我得到lat lng了位置。现在,react-geocode我可以获取单个地名,lat lng但是我想在map函数中使用该名称来获取地名。因此,正如我们所知道的那样,async我必须async await在那边使用。
这是代码
import Geocode from "react-geocode";

} = this.props
return (

await Promise.all(_.get(this.props, 'getCompanyUserRidesData', []).map(async(userRides,index) => {

但是,当我在此处将map函数与async一起使用时,它不会返回任何内容。谁能帮我解决我的问题?
