jQuery seems to be mindlessly injected into the vast majority of web applications and libraries. In some cases, there there may be no logical reason for pulling in jQuery as a dependency. For example: a library that only needs to perform a few simple element selections or DOM manipulations. Many web developers don’t really know when they need to use jQuery, and when they don’t. Pulling in this dependency seems to be a standard step when setting up a new library or web application. You shouldn’t be a jQuery developer, you should be a web developer, and part of being an effective web developer is a firm grasp on the underpinnings of web development.

For both beginning and experienced programmers! From the author of the multi-award-winning Thinking in C++ and Thinking in Java together with a member of the Kotlin language team comes a book that breaks the concepts into small, easy-to-digest "atoms," along with exercises supported by hints and solutions directly inside IntelliJ IDEA!
C++20 is the next big C++ standard after C++11. As C++11 did it, C++20 changes the way we program modern C++. This change is, in particular, due to the big four of C++20: ranges, coroutines, concepts, and modules.
The book is almost daily updated. These incremental updates ease my interaction with the proofreaders.

Java OOP Done RightAlan Mellor
Object Oriented Programming is still a great way to create clean, maintainable code. But only if you use it right.
This book gives you 25 years of OO best practice, ready to use.
You'll learn to design objects behaviour-first, use TDD to help, then confidently apply Design Patterns, SOLID principles and Refactoring to make clean, crafted code.
