Get All Unique Values In A JavaScript Array (remove Duplicates)

To get all unique values in a JavaScript array and remove duplicates, you can use the Set object. Here’s an example:

const array = [1, 2, 2, 3, 4, 4, 5];

const uniqueArray = [...new Set(array)];

console.log(uniqueArray); // Output: [1, 2, 3, 4, 5]

In the above example, a Set object is created using the new Set(array) syntax, where array is the original array. The spread operator ... is used to convert the Set object back into an array. This results in removing any duplicate values and creating a new array uniqueArray with only the unique values.
