jQuery.unique on an array of strings

Question

The description of jQuery.unique() states:

Sorts an array of DOM elements, in place, with the duplicates removed. Note that this only works on arrays

Answer 1

If not limited using jQuery, consider to use Set from ES6.

var arr = ['foo', 'bar', 'bar'];
Array.from(new Set(arr)); // #=> ["foo", "bar"]

Working for Firefox 45, Safari 9 and Chrome 49.
