each_with_index to iterate of items using index

We have already used each method of Ruby Array. Ruby Array also has a method called each_with_index. If we use each_with_index then besides getting the value we also get the index (position) of the value in the array.

When we use each_with_index then we also get the position of the each value.

Note that first position is zero. Our users might not like the first position as zero. This is how we can fix it.
