Ruby Ruby Basics (Retired) Ruby Strings Whitespace

I thought that "puts string" went after the string to make it appear in the console

one of the questions in the ruby basics on strings is that the following line of code would create a string with three lines.

string = "Hello
my name is Jason
and I like ruby"

I thought that in order for the code to show up correctly in the console it had to end with a puts string outside quotation marks.

string = "Hello
my name is Jason
and I like ruby"

puts string

did I just misread the question, or do you not need the <code> puts string</code> at the end of the document?

irb is a REPL environment, it, by default, always echoes and printout the value of every expression you enter, with or without the use of puts, that's what REPL is all about.

However, if you put the ruby code into a rb file, and compiles it using ruby file.rb, nothing will be printed on the screen unless the puts statement is used.
