right async flow

const request = require('request');
const async = require('async');

function send(data, cb) {
    request(data, (err, res, body) => {
        if (!err && (res.statusCode > 0 && res.statusCode < 400)) {
            return cb && cb(null, body)
        }
        if (!err && (res.statusCode >= 400 || res.statusCode <= 0)) {
            console.error(res.statusCode)
            return cb && cb("status " + res.statusCode)
        }
        if (err) {
            console.error(err.toString())
        }
        cb && cb(err);
    });
}

//right way to control async flow
async.timesLimit(1000, 10, (index, cb)=>{
    async.retry({times: 3, interval: 100}, (cb)=> {
        send({
            uri: "http://jsonplaceholder.typicode.com/posts",
            method: 'POST',
            json: true,
            followAllRedirects: true,
            body: {
                title: 'foo',
                body: 'bar',
                userId: 1
            },
            timeout: 5000
        }, cb)
    }, cb);
}, (err)=>{
    console.log("done")
})
