FAQs

This is useful in situations where you need to retry while iterating for example:

  • 10.times do |i| puts "Iteration #{i}" redo if i > 2 end.
  • 10.times do |i| begin puts "Iteration #{i}" raise if i > 2 rescue retry end end.
  • [job_1, job_2, job_3, job_4].each do |job| redo unless job.call == :success end.

To skip the loop's next iteration, use the Ruby next statement. There will be no more iterations when the next statement is executed. In other languages, the next statement is equivalent to the continue statement.
