Show recently added record at top in vuejs

There is a image upload functionality in my vuejs application.
The image upload works good and the uploaded recorded is also displayed.
But this recently added record get displayed at last in my list. On page refresh it appears at top.
I want to show the recently uploaded image at top as soon as after successful upload.
I have been trying really hard for this since 2 days and couldn't find the solution.
Please help. Vuejs version is 2
basically if I'm correct what you want is to push new images to the images array, for this just use unshift()
something like this
this.images.unshift('url_or_info_of_the_new_image')
Here, you do have an example of code showing you how you could achieve this.
https://codesandbox.io/s/gracious-tree-nig54?file=/src/App.vue
Essentially, the most interesting part is this.initialArray = [this.newValue, ...this.initialArray].
Also, depends on what you've tried until now but keep in mind the few caveats JavaScript does have with VueJS v2: https://v2.vuejs.org/v2/guide/reactivity.html#For-Arrays

React native DatePickerAndroid clear option

I'm using the native DatePickerAndroid for editing a date field in my react-native app.
I would like to know if there is any support for adding a 'clear' button to the native date picker that will close the datepicker and return an empty date - in order to be able to clear the date in the input field.
I've attached a screenshot of the native android date picker opened from a regular <input/> with type date in chrome. As you can see there is a 'clear' button - exactly what I'm looking for!
Actually this question was previously answered by ufxmeng, but his answer was lately deleted (I don't know why...).
His solution was to create a custom AndroidDatePicker module, mostly copied from the original DatePicker Module created by React Native, with slight changes for adding a CLEAR button.
He put together a github repo holding all files that need to be added/changed to accomplish this. Basically the changes you'll need are here and here.
But note that the original CLEAR button added in that repo doesn't fully match the needs pointed out in my question (see this issue).
So I've changed some of the code to make it work the way I expected. You could see the changes I made in this pull request
It works great for me!
In case anyone else needs this, I forked the original repo of ufxmeng and added Clear button functionality for TimePicker as well:

Imgur API v3 - Retrieve Image/Album comments

I'm developing a Windows Phone unofficial client for Imgur, the documentation talks about Comments endpoints/data models...but there isn't any method to retrieve comments about a specific image or album.
Anyone known how to retrive them...if is possible? Thanks
After a month I understand how to retrieve them: just putting "/comments" after album or image id. Stupid incomplete API documentation.
To clarify I want to add few things:
Indeed You need to put '/comments', so in the end Your url should look like:
https://api.imgur.com/3/gallery/cUkfS9L/comments/best.
The id ('cUkfS9L' here) may be the id of IMAGE, not only gallery.
But what's more important, and where I had a problem:
It looks like this doesn't work for newest images.
I tried it for a list of newest images (got by '(...)time/all(...)' sorting in query) and noticed that getting comments works for like 4th page of my images.
My solution was changing "time/all" to "top". Now I had much older images and getting comments worked well for them.
