bookVariables

In the previous example you used something called variable (in that specific example the variable was called "person").

Variable is a reserved memory location to store value (stored value can be of various allowed types). You can assign variable once and print it (or otherwise manupulate it) as many times as you want later!

Task

Analyze the code snippet on the right! Replace ___ symbols in line 1 with proper variable name (the one that used in the lines below) so that the program prints lyrics from Rick Astley's timeless hit "Never Gonna Give You Up"

Everything was clear?

How can we improve it?

Thanks for your feedback!
