Remove duplicate values in an array via `Set()`

Remove duplicate values in an array via Set()

If you want to remove duplicates from an array there is no specific array method for removing duplicate elements but you can achieve this using destructuring, the Set() function and recreating the array. It means that the original array will not change.

const array = ['a', 'b', 'c', 'b', 'd', 'e', 'a']
const unique = [...new Set(array)]
// [ 'a', 'b', 'c', 'd', 'e' ]
