This book explains the know-how of type definitions. The cover has some scratches and scuffs, but there are no problems with reading it. The contents are as follows: This book is for systematically learning about TypeScript's "type system." It is aimed at people who have some experience building applications with TypeScript and JavaScript, so it does not provide the know-how necessary for application construction. It focuses on TypeScript's type system and explains it in more depth, from its basics to how to use it in conjunction with frameworks. By reading this book, you should understand that "TypeScript is the best partner, indispensable for developing high-quality services quickly." Just as using good libraries doesn't automatically create a good application, type definitions also depend on individual skill and ideas. This book is the perfect book for those aiming to improve their "type definition" skills. #KenbunYoshii #Kenbun_Yoshii #book #Electrical/Mechanical/ElectronicCommunication #javascript #typescript #nuxt #nuxt.js #programming #webprogramming #webprogram"
