Remove first Item of the array (like popping from stack)

Removing the first item from an array in JavaScript: The Ultimate Guide 🚀

So, you have an array and you want to remove the first item from it. Maybe you're working with AngularJS and you're using the ng-repeat directive to display a list of items. You've also added a "Delete" button to remove items from the array, but it's currently removing the last item, one by one. You want to change it so that it removes items starting from the first item.

Well, fear not! We're here to guide you through this common issue and provide you with easy solutions. Let's dive in! 💪

The Problem 😕

The code snippet you've shared shows that you're using the indexOf method to find the index of the item you want to remove and then using the splice method to remove it from the cards array. However, this approach removes the item from the array starting from the index you provide, which is why it's removing the last item.

The Solution 🎉

To remove the first item from the array, you need to modify the index passed to the splice method. Instead of using the index of the item in the array, you should always remove the item at index 0. Here's how you can do it:

$scope.remove = function() {
  $scope.cards.splice(0, 1);
}

This code will remove the first item from the cards array every time the remove function is called. Voila! 🎩

Conclusion 🌟

By modifying the index passed to the splice method, you can easily remove the first item from an array. Now you can confidently remove items from the top and say goodbye to removing from the bottom! 🙌
