Benchmark: _.filter vs array filter - fork

HTML Preparation code:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.20/lodash.core.min.js"></script>

Script Preparation code:

var small_number_set = Array(10).fill(0).map(_ => Math.floor(Math.random() * 1000));

var medium_number_set = Array(1000).fill(0).map(_ => Math.floor(Math.random() * 1000));

var large_number_set = Array(1000000).fill(0).map(_ => Math.floor(Math.random() * 1000));

Tests:

large_number_set ---- _.filter
_.filter(large_number_set, num => num % 3 === 0)
large_number_set ---- array filter
large_number_set.filter(num => num % 3 === 0)
medium_number_set ---- _.filter
_.filter(medium_number_set, num => num % 3 === 0)
medium_number_set ---- array filter
medium_number_set.filter(num => num % 3 === 0)
small_number_set ---- _.filter
_.filter(small_number_set, num => num % 3 === 0)
small_number_set ---- array filter
small_number_set.filter(num => num % 3 === 0)
