Lodash loop through an array of arrays

I have an array with other arrays

[ ["1","13052033555","4444444","40000",1461575799,"1"],

Question: Using Lodash how can I loop through the values of each inner array and only apply a method to the 5th and 2nd?

If you want, instead (sorry, your question isn't clear), apply a method to each element of the second and fifth array you do something like this:

for (let i = 0; i < arr[2].length; i++) {

for (let i = 0; i < arr[5].length; i++) {
