Benchmark: find() vs for...of vs for-loop vs reverse-for

HTML Preparation code:

<div id='test'></div>

Script Preparation code:

var arr = [
  {text: "foo"},
  {text: "bar"},
  {text: "baz"},
];

Tests:

for-loop
let val; for(var i=0; i<arr.length; i++){ var value = arr[i]; if (value.text === 'baz') { val = value; break; } }
for..of
let val; for (var value of arr) { if (value.text === 'baz') { val = value; break; } }
Array.find()
let val = arr.find(node => node.text === 'baz');
reverse for
let val; for(var i=arr.length-1; i>-1; i--){ var value = arr[i]; if (value.text === 'b') { val = value; break; } }
