This book would not have happened without a call from an amazing editor, Louise Corrigan, whose enthusiasm for me to write another book was irresistible. I also have to acknowledge my family, who tolerated time spent away from them while I researched, coded, and wrote this book. Without their patience, I would not have been able to finish. Finally, thanks to you, the reader, whose interest in React has led you here to begin your React journey. Enjoy!
