Script Preparation code:

var arr = [];
var res = [];

for( var cpt = 0; cpt < 1000; cpt++ ) {
  arr.push(Math.random());
}

Tests:

Simple for loop - Access index and value
res = []; const len = arr.length; for(let i = 0; i < len; ++i) { res[i] = arr[i]; } console.log(res);
Array.forEach - Access index and value
res = []; arr.forEach((value, i) => { res[i] = value; }); console.log(res);
for-of + Array.entries
res = []; for(const [i, value] of arr.entries()) { res[i] = value; } console.log(res);
for-of - Access value only
res = []; for(const value of arr) { res.push(value); } console.log(res);
Simple for loop - Access value only
res = []; const len = arr.length; for(let i = 0; i < len; ++i) { res.push(arr[i]); } console.log(res);
Array.forEach - Access value only
res = []; arr.forEach((value) => { res.push(value); }); console.log(res);
