Does node.js have equivalent to window object in browser
提问by IGRACH
What I mean is does node.js have object that are global function methods of. Like this in browser:
我的意思是 node.js 是否具有作为全局函数方法的对象。在浏览器中是这样的:
function myGlobalFunction() {
console.log(this === window);
}
myGlobalFunction();
=> true

The closest equivalent in node is global. I'm not sure if it translates in all of the same ways, but if you open a REPL and type in this === global, it will return true.
node 中最接近的等价物是global。我不确定它是否以所有相同的方式翻译,但是如果您打开 REPL 并输入this === global,它将返回 true。
Here's a discussion on the global object, though some it the information may be deprecated as it's pretty old: 'Global' object in node.js
这是关于全局对象的讨论,尽管有些信息可能已被弃用,因为它已经很旧了:node.js 中的“全局”对象

Yes, the globalvariable is the global object in Node.js
是的,global变量是 Node.js 中的全局对象
From the docs:
从文档:
global# {Object} The global namespace object. In browsers, the top-level scope is the global scope. That means that in browsers if you're in the global scope var something will define a global variable. In Node this is different. The top-level scope is not the global scope; var something inside a Node module will be local to that module.
global# {Object} 全局命名空间对象。在浏览器中,顶级作用域是全局作用域。这意味着在浏览器中,如果您在全局范围 var 中,则会定义一个全局变量。在 Node 中这是不同的。顶级作用域不是全局作用域;节点模块中的 var 某些内容将是该模块的本地内容。
