How do Jacob and Warschauer describe the underlying difference between computer science and computational thinking?

Computer science is the study of computer hardware and software, algorithms, and programs, whereas computational thinking focuses on the problem$-$solving skills that are unique to programming, such as abstraction$.$

Computer science focuses more on the hardware$-$side of computing, whereas computational thinking focuses more on the programming language$-$side of creating software.

Computer science is the study of automation, whereas computational thinking is the study of abstraction$.$

Computer science is the study of programming languages, whereas computational thinking involves understanding the underlying logical features of these programming languages.
