Although it looks promising, a TypeScript edition of the GoF Design Patterns book, it actually done without much thought of the target language. There is too much focus on how to install and compile TypeScript code, while the actual Design Pattern part is weak at best.
The examples are very c++ like, and follow the original book to a fault. The examples are confusing and outdated, and the source code doesn’t even follow good TypeScript “linting” best practices.
I was expecting a much more thoughtful adaptation where the proper concepts of the original GoF patterns are applied to modern TypeScript concepts, with some real life examples etc.
For example, JavaScript has an actual concept of a Proxy object, and instead of using this for the Proxy example, the author is using a very confusing and unrealistic example of a Proxy for most TypeScript developers.
Finally, the intro for each design pattern is lacking good explanation of the rational behind it, and or the motivation to define and use it at all.
