Question

I have the following:

@books.each do |book|
... stuff
end

I’m curious to learn. How can I update the above to do something like loop through @books but not more than 6 times, MAX/ceiling of 6?

Thanks

Answer 1

The easiest way to do this is to take a slice of the Array and iterate over that:

@books[0,6].each do |book|
  # ...
end

The alternative is to keep the Array intact and bail out of the loop when you’re done:

@books.each_with_index do |book, i|
  break if (i == 6)

  # ...
end
