JS array: Remove duplicate values from

mobin12 · 17 Ağustos 2023

I have a Very Basic array of JavaScript that might or might not have duplicates.

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"]; i need to get rid of duplicate values and add the unique One S to a New array.

I could list every piece of code I've ever used, but since they all fail, I don't believe it's worth it. I also accept jquery-based solutions.

Here are a few ways to remove duplicate values from an array in JavaScript:
I have used this example from here: How to remove Duplicates from Array
Using a Set

JavaScript:

var names = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];

// Create a set to store the unique elements of the array.
const uniqueNames = new Set(names);

// Get the array of elements in the set.
const newNames = Array.from(uniqueNames);

console.log(newNames); // ["Adam", "Jenny", "Carl", "Mike", "Matt"]

This code works by first creating a set to store the unique elements of the array. Then, it gets the array of elements in the set and returns it.
