I dont understand how #{…} construct is used in Ruby.
I’ve seen in used in the regexp example on http://www.ruby-doc.org/core-1.9.3/Regexp.html
place = "tokyo"
/#{place}/.match("Go to tokyo")
#=> #<MatchData "tokyo">
What exactly is this #{…} feature called and does anyone know of some good working examples of this.
Really appreciate the help.
Thanks!
