async-cycle

Map over promises serially

This is an asynchronous loop of the serializer. Provide two methods: asyncWhile/asyncMap, the former can end the loop early and the latter cannot。 这是序列化器的异步循环。提供两种方法:asyncWhile/asyncMap，前者可以提前结束循环，而后者不能。

Install

$ npm install async-cycle

Usage

const { asyncMap, asyncWhile } = require ('async-cycle');
 
const keywords = [
    'Jack',

const createPromise = async (value) => {
    return new Promise(r => {
        r(value);
    });
};
 
(async () => {
    await asyncWhile(keywords,async value => {
       return createPromise(value);
    });
    //[Jack]
    
    await asyncMap(keywords,async value => {
        return createPromise(value) ;
