JavaScript add objects to array and iterate

Question

I'm using express framework to grab links from some webpage, and I add this links to Array. I'm using async to print final result but when I print my array I gets list of objects.

Result of collate function:

Finall: [object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Objec
t] 

How can I iterate of this array of objects? This is my code:

router.route('/send')
 .post(function(req, res){
 async.series([ function(callback){
 var url = req.body.url;
 var items = [];
 console.log(url);
 if(url.length>=1) {
 if (isURL(url)) {
 console.log('OK');
 res.sendStatus(200);
 request(url, function(err, resp, body){
 $ = cheerio.load(body);
 links = $('a.offer-title');
 $(links).each(function(i, link){
 items[i] = new itemParam($(link).text(),12)
 });
 callback(false, items);
 });
 } else {
 errorHandling(res, 401,"Invalid url");
 }
 }else{
 errorHandling(res, 401,"Invalid url");
 }
 }
 ],
 /*
 * Collate results
 */
 function(err, p) {
 console.log("Finall: " + p[0]);
 }
 );
 });

• Bergi: uh, have you tried a loop?
• lukassz: Yes I try with for loop. ` for (var key in p) { if (p.hasOwnProperty(key)) { console.log(key + " -> " + p[key]); } }`
• Bergi: WTH are you using async.series here? Also, you should always call callback instead of jumping into errorHandling right away.
• lukassz: I am new to this topic. What exactly should I use?
• Bergi: It's an array, so you should use an array loop. Also, it seems you need to iterate over p[0], not over p.

here's one simple way to do this:

const request = require('request'),
 cheerio = require('cheerio')
const scrape = (url) => {
 return new Promise((resolve, reject) => {
 let links = [] // collect all links here
 request(url, (err, res, body) => {
 if (err) {
 return reject(err)
 }
 let $ = cheerio.load(body)
 $('a').each(function () { // use any selector you like
 links.push($(this).attr('href')) // ...and extract whatever you like
 })
 resolve(links)
 })
 })
}
scrape('http://google.com?q=javascript')
 .then(links => {
 // handle links
 console.log(links)
 })
 .catch(err => {
 // handle error
 })
