What is the purpose of do!

In the while loop I see that, with or without do it works the same way. Can you please point to some resource regarding this?

Hi,

I have never coded in ruby, so I went to http://www.tutorialspoint.com/ruby/ruby_loops.htm to find an answer. In while loop, do is the separator between the conditional and code. In other loops it is optional, as the separator can either be "do", ";" or a new line.

Hi, Thanks for your answer, yes it might be optional. But not a separator

Like I said, I never coded in ruby.

In the aricle I linked

Ruby until Statement:

until conditional [do]
   code
end

Executes code while conditional is false. An until statement's conditional is separated from code by the reserved word do, a newline, or a semicolon.

That's why I named it a separator
