Best way to search through an Object containing multiple objects and arrays

Question

I have tried a couple of methods using indexOf and if (x in y) none of which seem to do exactly what I want.

I need to pull through several objects and find a specific number / timestamp / Date depending on the object. Here is a screenshot of the console of my Object.

Any thoughts?

Specifically when I first get the data I extract all the Timestamps (posted on date / time) from the API Response(s). Using that Array of timestamps I am trying to find the most recent posted object from all the responses.

Here are some more screen captures:

Twitter created_at timestamp

Tumblr timestamp

and my dates array

And my code used to pull the information and sort it.

Don't mix different object types in the same array, but normalize them before. Also, you should not need to use a global blogs variable, instead use the Deferreds properly.

function handleTumblrResponse(data) {
    delete data.meta;          // actually, you don't
    delete data.response.blog; // need those
    var resultdates = [];
    for (var e=0; e<data.response.posts.length; e++)
        resultdates.push(data.response.posts[e].timestamp);
    return resultdates;
}
function handleTwitterResponse(data) {
    var resultdates = [];
    for (var e = 0; e<data.length; e++){
        var timesting = data[e].created_at;
        var date = Date.parse(time)/1000;
        resultdates.push(date);
    }
    return resultdates;
}
$.when(
    // those get… functions are the plain ajax calls, no success handlers
    getBitterSyndromeAjax().then(handleTumblrResponse),
    getMoundsMusicTumblr().then(handleTumblrResponse),
    getGateWayDrugSTLTumblr().then(handleTumblrResponse),
    getGateWayDrugSTLTwitter().then(handleTwitterResponse)
).done(function(bitterSyndrom, moundsMusic, drugsTumb, drugsTwit) {
    // concat the four arrays to one
    var dates = Array.prototype.concat.apply([], arguments);
    dates.sort(function(a,b){return b-a});
    // do something with the timestamps
});

Btw, I'm quite sure Date.parse cannot handle that odd Twitter format. Instead, use

function fromDateString(str) {
    var res = str.match(/(\S{3})\s(\d{2})\s(\d+):(\d+):(\d+)\s(?:([+-])(\d\d)(\d\d)\s)?(\d{4})/);
    if (res == null)
        return NaN; // or something that indicates it was not a DateString
    var time = Date.UTC(
      +res[9],
      {"Jan":0,"Feb":1,"Mar":2, …, "Dec":11}[res[1]] || -1,
      +res[2],
      +res[3],
      +res[4],
      +res[5], 
    );
    if (res[6] && res[7] && res[8]) {
        var dir = res[6] == "+" ? -1 : 1,
            h = parseInt(res[7], 10),
            m = parseInt(res[8], 10);
        time += dir * (h*60+m) * 60000;
    }
    return time;
}
