Benchmark: lodash uniq vs Array.from(new Set()) vs spread new Set() vs for vs for memory optimized 2

HTML Preparation code:


<script src='https://cdn.jsdelivr.net/npm/lodash@4.17.10/lodash.min.js'></script>

Script Preparation code:

let array = [];
for (let i = 0; i < 100000; i++) {array.push(~~(Math.random() * 2000))}

Tests:

Spread
return [...new Set([1, 2, 3, 4, 5, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7])]
use lodash
return _.uniq([1, 2, 3, 4, 5, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7]);
Array.from
return Array.from( new Set([1, 2, 3, 4, 5, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7]) );
For
const visited = {}; const uniques = []; const initial = [1, 2, 3, 4, 5, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7]; for(let i=0;i<initial.lenght;i++){ if(!visited[initial[i]]) { visited[initial[i]] = true; uniques.push(initial[i]); } } return uniques
For memory optimized
const visited = {}; const uniques = []; const initial = [1, 2, 3, 4, 5, 6, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7]; for(let i=0;i<initial.lenght;i++){ if(!(initial[i] in visited)) { visited[initial[i]] = undefined; uniques.push(initial[i]); } } return uniques
