var array = Array.from({length: 40}, () => Math.floor(Math.random() * 140));

Tests:

Set spread
const f = [... new Set(array)]
const f = [... new Set(array)]
Array from set
const s = new Set(array) const l = Array.from(s)
const s = new Set(array)
const l = Array.from(s)

const b = array.filter((i,index) => array.indexOf(i)=== index)

 
const b = array.filter((i,index) => array.indexOf(i)=== index)

filter 2
const b2 = array.filter((i,index, arr) => arr.indexOf(i)=== index)
const b2 = array.filter((i,index, arr) => arr.indexOf(i)=== index)

var ar2 = [];
array.forEach(i => {
	if (!ar2.includes(i)) {
      ar2.push(i);
    }
});

 
var ar2 = [];array.forEach(i => {    if (!ar2.includes(i)) {      ar2.push(i);    }});
