Removing Duplicates from an Array using JavaScript

In this article, we will discuss how to remove duplicates from an array using JavaScript.

Code Implementation

Here is a simple JavaScript function that removes duplicates from an array:

        
            function removeDuplicates(arr) {
                return [...new Set(arr)];
            }

            // Sample array with duplicates
            const array = [1, 2, 3, 4, 1, 2, 5];

            // Call the function to remove duplicates
            const result = removeDuplicates(array);

            // Print the result
            console.log(result); // [1, 2, 3, 4, 5]
        
    

As shown in the code snippet above, we define a function removeDuplicates that takes an array as input and uses the Set object to remove duplicates. Finally, we convert the Set object back to an array using the spread operator [... ].

Conclusion

Removing duplicates from an array is a common task in programming. By using the Set object in JavaScript, we can easily remove duplicates from an array and obtain a new array with unique elements.
