Solution: Hello, Interpolation!
Here is a possible solution to this problem:
my $name = prompt 'What is your name? '; say "Hello, $name!";
🦋 You can find the source code in the file hello-interpolation.raku.
Run the program, and it will enter a mode when it waits for your input. After you type the name and press Enter, the program continues and prints the greeting:
$ raku exercises/strings/hello-concatenation.raku What is your name? Raku Hello, Raku!
Notice that this time, the string is double-quoted. In double quotes, variables are interpolated, so their content is placed in the string.
