Tests:

foreach with callBack
arr.forEach(item => { doSomething(item); });
foreach
arr.forEach(doSomething);
for with keeping length
const length = arr.length; for (let i = 0; i < length; i++) { doSomething(arr[i]); }

for (let i = 0; i < arr.length; i++) { doSomething(arr[i]); }
for / of
for (const value of arr) { doSomething(value); }
for / in
for (const value in arr) { doSomething(value); }
map
arr.map(doSomething);
