JavaScript: Best way to remove duplicates in JS Array

Hello, folks!

1) Remove duplicates from an array using a Set

A Set is a collection of unique values. To remove duplicates from an array:

• First, convert an array of duplicates to a Set. The new Set will implicitly remove duplicate elements.
• Then, convert the set back to an array.
• The following example uses a Set to remove duplicates from an array:

let dublicates = ['A', 'A', 'A', 'B', 'C', 'C'];
let uniqueChars = [...new Set(dublicates)];

Output:

[ 'A', 'B', 'C' ]
