当JavaScript 看到对Person类访问name属性时,它会检查Person类是有name属性。 如果没有,JavaScript 会检查 Person 类是否有绑定到name属性的方法。在此示例中,name()方法通过关键词get绑定到name属性。一旦 JavaScript 找到 getter 方法,它就会执行 getter 方法并返回一个值。
It is with much happiness that I think I can finally say, without seeming like a fool, that: “JavaScript Getters and Setters are now prevalent enough to become of actual interest to JavaScript developers.” Wow, I’ve been waiting a long time to be able to say that....
the return value from the getter is used. When a value is set, the setter is called and passed the value that was set. It's up to you what you do with that value, but what is returned from the setter is the value that was passed in – so ...
Not many people know it, but you can use "real" getters and setters in JavaScript if you want to. De-facto offerings Firefox 2.0+, Safari 3.0+, Google Chrome 1.0+ and Opera 9.5+ support a de-facto way of getters and setters: var lost = { loc : "Island",

The concept of getters and setters in JavaScript is just one of those things you should understand. They are nice in jQuery because the API is so consistent that once you get it, you can pretty much just guess how it is going to work for various methods. At the most basic level…...

JavaScript Proxies function in a similar way compared to Getters and Setters — the only difference is you don’t have to create a wrapper function around it. Here’s the same code from above but with Proxies. let state = { show = false } state = new Proxy(state, { get(target, prop...
