Script Preparation code:

var array = Array.from({ length: 60 }, () => Math.floor(Math.random() * 140));

var filterF = function(arr) { return arr.filter((a, b) => array.indexOf(a) === b) }
var filterS = function(arr) { return [...new Set(array)] }
var sf = function(arr) { return Array.from(new Set(arr)) }

Tests:

Filter
const a = filterF(array)
Set spread
const b = filterS(array)
From set
const c = sf(array)
