Script Preparation code:

var array = Array.from({length: 410}, () => Math.floor(Math.random() * 140));

var arrayA = Array.from({length: 410}, () => Math.random().toString(36).substring(2, 15));

var arrayS = Array.from({length: 40}, () => Math.floor(Math.random() * 140));

var arraySA = Array.from({length: 40}, () => Math.random().toString(36).substring(2, 15));

Tests:

Set spread num
const f = [... new Set(array)]
Array set small
const la = Array.from(new Set(arrayS))
Array set small string
const la = Array.from(new Set(arraySA))
For small
const sa ={} const lca = [] for(let i =0; i < arrayS.length; i++){ if (sa[arrayS[i]]) { continue } sa[arrayS[i]] = 1 lca.push(sa[arrayS[i]]) }
For string small
const sa ={} const lca = [] for(let i =0; i < arraySA.length; i++){ if (sa[arraySA[i]]) { continue } sa[arraySA[i]] = 1 lca.push(sa[arraySA[i]]) }
Create set small
const scsdf = new Set(arrayS)
Create set small string
const scsdfa = new Set(arraySA)
Filter number small
const baas = arrayS.filter((i,index) => arrayS.indexOf(i)=== index)
Filter string small
const baa = arraySA.filter((i,index) => arraySA.indexOf(i)=== index)
Filter string
const ba = arrayA.filter((i,index) => arrayA.indexOf(i)=== index)
Create set string
const sc = new Set(arrayA)
For string
const sa ={} const lca = [] for(let i =0; i < arrayA.length; i++){ if (sa[arrayA[i]]) { continue } sa[arrayA[i]] = 1 lca.push(sa[arrayA[i]]) }
Array set string
const la = Array.from(new Set(array))
Set array
const z = [... new Set(arrayA)]
For
const s ={} const lc = [] for(let i =0; i < array.length; i++){ if (s[array[i]]) { continue } s[array[i]] = 1 lc.push(s[array[i]]) }
Create Set
const ss = new Set(array)
Filter
const b = array.filter((i,index) => array.indexOf(i)=== index)
Array from set
const l = Array.from(new Set(array))
Spread set small
const z = [... new Set(arrayS)]
Spread set small string
const z = [... new Set(arraySA)]
