Eliminating Duplicates Values from Arrays

Removing duplicate values is simple.

We just convert it to a set and then spread it back to an array.

For instance, we can write:

const arr = ['foo', 'bar', 'foo'];
const uniqueArr = [...new Set(arr)];

Then we get [“foo”, “bar”] as the value of uniqueArr .

This won’t work with objects since only objects with the same reference are considered the same.
