Ruby Loops: When and When not to put "do"

I recently was working with loops in Ruby and I've tested my code on online compilers and I've noticed that when doing an Until loop, the loop can function correctly with or without the keyword do next to it. Why is that so? Is the do keyword necessary? Can I leave do out? If I leave the keyword out is it considered bad practice?

In my experience programming ruby in professional settings most people use the do keyword, and is some cases it is necessary such as

["some","stuff","in","here"].each do |x|
  puts "#{x}"
end
