Remove Items From Array With Splice In For Loop Duplicate

So, you want to remove duplicate items from an array using the `splice` method within a `for` loop, huh? Well, you've come to the right place! This article will guide you through the process step by step to help you clean up your array like a pro.

First things first, let's break down the problem. When working with arrays, it's common to encounter duplicates that you'd like to get rid of. The `splice` method comes in handy because it allows you to change the contents of an array by removing or replacing existing elements.

To remove duplicates from an array using `splice` within a `for` loop, you'll need to follow these steps:

1. Create a new array to store the unique elements without duplicates.
2. Use a `for` loop to iterate over the original array.
3. Check if the current element is already present in the new array.
4. If the element is not a duplicate, add it to the new array.
5. After iterating over the entire original array, assign the new array back to the original array to replace the duplicates with unique elements.

Here's a simple code example to illustrate this process:

let originalArray = [1, 2, 3, 2, 4, 5, 3];
let newArray = [];

for (let i = 0; i < originalArray.length; i++) {
    if (newArray.indexOf(originalArray[i]) === -1) {
        newArray.push(originalArray[i]);
    }
}

originalArray = newArray;

console.log(originalArray); // [1, 2, 3, 4, 5]

In this code snippet, we create a new array `newArray` to store unique elements. We then loop through the `originalArray`, checking if the element is not already present in `newArray`. If it's not a duplicate, we add it to `newArray`. Finally, we assign the `newArray` back to the `originalArray` to replace the duplicates.

By following this approach, you can efficiently remove duplicates from an array using `splice` in a `for` loop. It's a simple yet effective way to clean up your data and ensure that your array contains only unique elements.

Remember, when working with arrays and manipulating their contents, taking a systematic approach like this can save you time and effort in the long run. So, give it a try and see how you can streamline your code by removing duplicates like a pro!
