Benchmark: Unshift value in array - Lodash partition vs Reduce vs 2 Filter

HTML Preparation code:

<script src='https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.min.js'></script>

Script Preparation code:

var tabl = Array.from({ length: 10000 }).map((value, i) => i)

Tests:

Lodash
const [a, b] = _.partition(tabl, e => e === 900); const newArr = [...a,...b];
Reduce
const newArr = tabl.reduce((prevArr, currVal) => {if(currVal === 900) {return [currVal, ...prevArr]} else {return [...prevArr, currVal]}}, [])
2 Filter
const a = tabl.filter(e => e === 900); const b = tabl.filter(e => e !== 900); const newArr = [...a,...b];
