Script Preparation code:

   var arr = [];
    for (var i = 0; i < 100000; i++) {
      arr[i] = i;
    }
  
    function someFn(i) {

   var arr = [];    for (var i = 0; i < 100000; i++) {      arr[i] = i;    }      function someFn(i) {      return i * 3 * 8;    }

Tests:

const res = []
arr.forEach(function (item){
  res.push(someFn(item))
})

 
const res = []arr.forEach(function (item){  res.push(someFn(item))})

const res = []
for (var i = 0, len = arr.length; i < len; i++) {
  res.push(someFn(arr[i]))
}

 
const res = []for (var i = 0, len = arr.length; i < len; i++) {  res.push(someFn(arr[i]))}

const res = []
const len = arr.length;
for (var i = 0; i < len; i++) {
  res.push(someFn(arr[i]))
}

 
const res = []const len = arr.length;for (var i = 0; i < len; i++) {  res.push(someFn(arr[i]))}

const res = arr.map(item => someFn(item))

 
const res = arr.map(item => someFn(item))

const res = [] 
for (const el of arr) {
   res.push(someFn(el))
 }
