[AISWorld] New Open Access textbook on JavaScript web apps

[Gerd Wagner]

See http://web-engineering.info/JsFrontendApp/book.html

The focus of the book are general concepts and techniques concerning

  1) integrity constraints and data validation,
  2) unidirectional and bidirectional associations between object types,
  3) subtyping and inheritance.

The book can be used in web engineering courses for learning JavaScript
and how to implement basic OO concepts (such as enumerations, associations
and class hierarchies) and frontend web apps with plain JavaScript,
not using any (third-party) framework or library.
