通过上面ES6中的Class示例展示了JavaScript的继承实现,但是前面说了,JavaScript中不具备类的实际设计模式,即便是Class语法糖也还是基于Function和new机制来完成的,接着下面就是用ES5的语法来实现上面示例代码的同等功能(仅仅实现同等功能,不模拟Class实现,在解析class博客中再写): ES5中Function基于构造与原型实现类与对象...
since we need to call Class.class instance method// // and have to avoid calling it in the static initializer of the Class class...// private static final Unsafe unsafe = Unsafe.getUnsafe();// // offset of Class.reflectionData instance field// private static final long reflectionDataOffset...
JavaScript objects are very simple collections of name-value pairs. There are two ways of creating a simple object in JavaScript. The first way is as follows:var obj = new Object(); And the second way is as follows:var obj = {}; We can also create an entire object, as follows:...

Again, JavaScript is different from C++/C#. To understand object methods, I first need to take a closer look at JavaScript functions. JavaScript Functions Are First Class In many programming languages, functions and objects are usually considered two different things. In JavaScript, this distinction...
JavaScript object is passed or returned to Java code, it is wrapped in an instance ofJSObject. When aJSObjectinstance is passed to the JavaScript engine, it is unwrapped back to its original JavaScript object. TheJSObjectclass provides a way to invoke JavaScript methods and examine JavaScript ...
JSOX is a(super-sub)set of JavaScript, although addsno new data types, andworks with all existing JSON content. Some features allowed in JSOX are not directly supported by Javascript; although all javascript parsable features can be used in JSOX, except functions or any other code construct, ...
