Can you share a screenshot of the actual usage?
I might be able to do that. One sec.
It's probably something funny with the data, but a screenshot of the usage might help rule out any silly errors.
Yeah, I wanted to make sure I was expecting the right stuff to happen.
Nope, that didn't work.
So that's the code, being debugged. You can see "theseOrders" is an array of non-empty objects.
Hmm, that url doesn't work for me
Can you just drag it into Gitter?

And there's the result of checking what "thisOrder" is. I expected it to be one of the non-empty objects. Is that a correct expectation?
I think it might just be confusion about how the debugger is working
I think you are not yet in the scope of the callback, you are still in the outer scope
It always comes back to scope. What would you recommend?
And thisOrder is not defined in the outer scope.
Just add a few new lines inside your callback so that it's easier to set a breakpoint in there.

Ah. I see what you mean.
It is populated now in the debugger, but not filtering as I expect it to.
What is the value of thisOrder?
Now that it's populated, it's the same as one of the entries in the theseOrders array.
It could be because I am edgily trying to compare Date Strings.
(is this one bigger than that one, etc.)
Yeah, that's probably not safe
What format is the date string?
one of them is yyyy-mm-dd and the other is yyyy-mm-ddThh:MM:ss
I would add console.log(a, b, a <= b)
My very quick research into ASCII codes told me that would PROBABLY work.
Yeah, it seems dangerous (you should probably try to find a better way), but i would expect it to work as well.

Apparently it doesn't work.
I was expecting 0 to evaluate to less than 2.

That's better. It still doesn't filter out the last two objects from the resulting array, though.
Well, that's all right. It's 5 here. I'm taking off. Thank you for your help!
I think I've got it to a working state. I appreciate it!
Great!
Have a good weekend.
I'm learning cordova right now and trying to use underscore's isEqual function. I understand it comes with cordovalib, does anybody know how i can use it in my index.js?
i also don't usually do webdev
I’m not familiar with Cordovalib. Do you have code you can share?
Fixed it: needed to npm install underscore, then copy underscore-min.js to platforms/[platform]/platform_www and do <script ... src="underscore-min.js"/> in my index.html
@captbaritone I was fetching an object from a server and checking equality locally
working on a custom version of cordova-plugin-fetch and was testing it in an app, so did this in my index.js:
tryFetch: function() {
var parentElement = document.getElementById("fetchjson");
var fetchingElement = parentElement.querySelector('.fetching');
var verifiedElement = parentElement.querySelector('.verified');
var invalidElement = parentElement.querySelector('.invalid');

fetchingElement.setAttribute('style', 'display:block;');
verifiedElement.setAttribute('style', 'display:none;');
invalidElement.setAttribute('style', 'display:none;');

// mvpnFetch should work, cordovaFetch shouldn't
//cordovaFetch('http://server.local/json.json')
mvpnFetch('http://server.local/json.json')
    .then(function(response) {
        return response.json();
    })
    .then(function(json) {
        console.log(json);
        fetchingElement.setAttribute('style', 'display:none;');
        if (_.isEqual(json.body, expectedJsonFromFetch)) {
            verifiedElement.setAttribute('style', 'display:block');
        } else {
            invalidElement.setAttribute('style', 'display:block');
        }
    })

}

const expectedJsonFromFetch = {
"hello": "world",
"number": 1,
"subobject": {
"key": "val"
},
"array": [
"one",
2,
true
]
}
