Utilize the built-in set data structure in JavaScript to remove duplicates from an array.
let numbers = [1, 2, 3, 4, 4];
let uniqueNumbers = [...new Set(numbers)];
To ensure all elements are unique within a collection, converting an array to a set is necessary. Sets contain only distinct values, unlike arrays which may include duplicates. This can be achieved by using the following code:
let numbers = [5, 6, 7, 8, 8];
let uniqueNumbers = new Set(numbers);
