📝 Angular ng-repeat in Reverse: A Simple Solution

Welcome to our tech blog! Today, let's dive into a common issue faced by Angular developers - how to get a reversed array in Angular using ng-repeat. 🔄

So, you want to display your data in reverse order without the need to sort it by a specific property. You might have thought of using the orderBy filter, but it requires a predicate to sort, which may not suit your needs. Let's explore a simple solution together! 💡

The Challenge

Let's take a look at the code snippet you've provided:

<tr ng-repeat="friend in friends | orderBy:'name':true">
      <td>{{friend.name}}</td>
      <td>{{friend.phone}}</td>
      <td>{{friend.age}}</td>
<tr>

The orderBy filter here is using the 'name' property as the sorting criterion and sets the reverse flag to true. However, you want to override this behavior and reverse the original array without sorting it.

The Solution

To achieve this, you can leverage the power of the Angular's filter filter! 🎉

<tr ng-repeat="friend in friends | filter: true | orderBy: '$index': true">
      <td>{{friend.name}}</td>
      <td>{{friend.phone}}</td>
      <td>{{friend.age}}</td>
<tr>

By using filter: true, we modify the array to contain all elements and maintain their original order. Then, we apply orderBy: '$index': true to sort the array by the $index property (the index of each element). The reverse flag is set to true to achieve the desired result - a reversed order of the original array.
