15-year-old girl sees void, publishes coding book for kids Coding book for kids, by a kid Danielle Park wrote a computer science and coding book geared towards kids, especially girls. She is 15 years old and a sophomore in high school. PARAMUS, N.J. - As a freshman at Paramus High School, Danielle Park took one look around her AP Computer Science Principles class and saw a huge void. "There was this really overwhelming feeling because I noticed the classroom is so male-dominated," Park said. Park, now a sophomore, was also inspired to make the subject she loves more accessible for everyone. So at 15, she became an author.
