How to create a unique list of elements using the Set object

Creating unique lists in javascript is a common task, this is usually achieved by applying filters or for loops, but there is another way to accomplish this leveraging the Set object.

const list = [1, 2, 3, 5, 2, 5, 7]; 
const uniqueList = [...new Set(list)];

We pass the array of primitive values to the Set object; it creates a collection of unique values which is then converted to a list using the spread operator syntax and array literals.
