Question

Hello I want to extract elements from both arrays with the same url .How can i loop these two arrays and get their content, because it gives me undefined for the news_url and i think it outputs twice the items in the console.

function geo(news_array,user_tweets){
    console.log(news_array,user_tweets);
    for (var x=0; x<user_tweets.length; x++) {
        var user = user_tweets[x].user;
        var date = user_tweets[x].date;
        var profile_img = user_tweets[x].profile_img;
        var text = user_tweets[x].text;
        var url=user_tweets[x].url;
        second(user,date,profile_img,text,url);
    }
    function second(user,date,profile_img,text,url){
        for (var i = 0; i < news_array.length; i++) {
            var news_user = news_array[i].news_user;
            var news_date = news_array[i].news_date;
            var news_profile_img = news_array[i].news_profile_img;
            var news_text = news_array[i].news_text;
            var news_url=news_array[i].url;
            if (url==news_array[i].news_url) {
                geocode(user,date,profile_img,text,url,news_user,news_date,news_profile_img,news_text,news_url);
            }
        }
    }
    function geocode(user,date,profile_img,text,url,news_user,news_date,news_profile_img,news_text,news_url) {
        console.log(url,news_url);
            }
    }

Answer 1

The problem is
in news_tweets function, you add news_url to news_array. So you should call

news_array[i].news_url

in second function.

I modify your code as

1. news_url: (item.entities.urls.length > 0)?item.entities.urls[0].url : '' in news_tweets function
2. add close brace } for geo function and remove } from last
3. add new_array parameter to second function like second(user, date, profile_img, text, url,news_array);
