要获取计算机的当前分辨率，你可以使用JavaScript中的`window.screen`对象

要获取计算机的当前分辨率，你可以使用JavaScript中的window.screen对象。这个对象包含了关于用户屏幕的信息，包括分辨率。以下是一个简单的示例代码，展示了如何获取并显示当前的屏幕分辨率：

// 获取屏幕宽度和高度
var screenWidth = window.screen.width;
var screenHeight = window.screen.height;

// 显示屏幕分辨率
console.log("当前屏幕分辨率为: " + screenWidth + "x" + screenHeight);

这段代码首先从window.screen对象中获取了屏幕的宽度和高度，然后通过console.log将分辨率信息输出到控制台。这样你就可以知道当前浏览器窗口所在的屏幕分辨率了。

Operator Overview
If you are a C, C++, or Java programmer, most of the JavaScript operators should already be familiar to you. Table 5-1 summarizes the operators; you can use this table as a reference. Note that most operators are represented by punctuation characters such as + and =. Some, however, are represented by keywords such as delete and instanceof. Keyword operators are regular operators, just like those expressed with punctuation; they are simply expressed using a more readable and less succinct syntax.
