In this book, the author describes effective programming practice for every programming task. The software used in this book is using VScode and typescript 4.2. So please use this book if you want to know about these technologies.
The typescript files end with .ts just like javascript files end with .js. The similartity between typescript and java script ends there.

In chapter 4 structural design patterns are discussed. In chapter 5 behavioural design patterns are discussed. The strategy, iterator, mediator patterns are discussed. UML class diagram sfor each kind of desing are provided in the book for each chapter. In chapter 6 functional programming with typescript is discussed. In chapter 7 reactive programming with typescript is discussed. Modern and robust applications can be developed using the singleton and the iterator pattern. This is discussed with an example. SOLID principles for OOP design are described in this chapter as single reponsibility principle, open close principles, liskov substitution principle, interface segregation principle and dependency inversion principle are coined here. In chapter 9 antipattern principles are discussed.
