I need help parsing JSON

When I console.log the data that I am getting, I'm getting an object that looks like this (I trimmed some stuff to make it look more readable and the ... is basically a repeat of the info with different values):

[ Submission {
    title: 'Untitled',
    content:
     { url: 'http://orig00.deviantart.net/8791/f/2016/079/7/b/untitled_by_wecode-d9vvg2w.png',
       height: '400',
       width: '400',
       medium: 'image' },
    text: null },
  Submission {
    ...
     },
  Submission {
    ...
     } ]

I want to grab the url from content in each submission. At the end, I should get an array with multiple urls. I'm working in nodejs if that is of any help.

var yourObject = [{
    Submission: {
        title: 'Untitled',
        content: {
            url: 'http://orig00.deviantart.net/8791/f/2016/079/7/b/untitled_by_wecode-d9vvg2w.png',
            height: '400',
            width: '400',
            medium: 'image'
        },
        text: null
    }
}];

// your new array of url's
var urls = [];

for (i = 0; i < yourObject.length; i++) {
    urls.push(yourObject[i].Submission.content.url);
}

Use .map, which creates a new array by applying the function to each element in the old array.

var arrayOfSubmissions = ...
var arrayOfURLs = arrayOfSubmissions.map(function(submission){
    return submission.content.url
})

.map is your friend. It iterates over every item of an array and will add whatever each run of a function returns to a new array.

var urls = yourArray.map(function (item) {
   return item.content.url;
});

So you have an array of Objects here - let's assume it's stored in a variable called myArray. To get a new list of just the URLs, you can do:

var listOfUrls = [];
myArray.forEach(function(obj) {
    listOfUrls.push(obj.content.url);
}

This will give you the array you want. This is a simple way to do it, but you can also do it in other ways such as map
