If you ve used a more traditional object-oriented language, such as C++ or Java, JavaScript probably doesn t seem object-oriented at all. It has no concept of classes, and you don t even need to define any objects in order to write code. But don t be fooled-JavaScript is an incredibly powerful and expressive object-oriented language that puts many design decisions right into your hands.In The Principles of Object-Oriented JavaScript, Nicholas C. Zakas thoroughly explores JavaScript s object-oriented nature, revealing the language s unique implementation of inheritance and other key characteristics. You ll learn:- The difference between primitive and reference values- What makes JavaScript functions so unique- The various ways to create objects- How to define your own constructors- How to work with and understand prototypes- Inheritance patterns for types and objectsThe Principles of Object-Oriented JavaScript will leave even experienced developers with a deeper understanding of JavaScript. Unlock the secrets behind how objects work in JavaScript so you can write clearer, more flexible, and more efficient code.
