Benchmark: array iteration vs _.each vs map vs set iteration

HTML Preparation code:

<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.11/lodash.core.js"></script>

Script Preparation code:

var array = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']
var set = new Set(array)

Tests:

_.each
_.each(array, (value, index) => { console.log(value) })
forEach
array.forEach((value, index) => { console.log(value) })
map
array.map((value, index) => { console.log(value) })
set forEach
set.forEach((value, index) => { console.log(value) })
set -> array _.each
_.each([...set], (value, index) => { console.log(value) })
