[Rails] Re: Skip index in array.each_with_index loop

Can anyone help me on how to skip index in ARRAY.each_with_index loop?

Please look at below case:

In a ARRAY.each_with_index loop, I would like increase the index by 10
whenever a condition is met.

arr is array of numbers from 0 to 50
arr.each_with_index do |x,i|
  if i % 10 == 0
    puts "#{x} at #{i}"
    i = i+10  //index increased by 10
  end
end

The output should be:
10 at 10
30 at 30
50 at 50

Thanks
Ajit

Could you explain it in a more clear way, "whenever a condition is met". If you just want to select the elements that meet some condition, use one of the following Array methods:

keep_if

select

reject
