Difference between '%{}', '%Q{}', '%q{}' in ruby string delimiters

Question

I was going through an online tutorial on ruby and found this \"General Delimited Strings\",

%{a word}  # => \"a word\"
%Q{a word} # => \"a word\"
%q{         


        

Answer 1

%q(no interpolation)

%Q(interpolation and backslashes)

%(interpolation and backslashes)

Example

$ str = 'sushant'

$ %q[#{str} "mane"]
 => "\#{str} \"mane\""

$ %Q[#{str} "mane"]
 => "sushant \"mane\""

$ %[#{str} "mane"]
 => "sushant \"mane\""
