'''String interpolation''' is a form of [[Quasi-quotation]], common in many [[programming language]]s which make heavy use of [[String_String (computer_sciencecomputer science)|string]] representations of data, such as [[Ruby (programming language)|Ruby]], [[PHP]], [[Perl]], etc. It means to insert a string or replace a variable with its value.
