javascript - 如何在窗口对象之外创建JavaScript对象？(How to create JavaScript object outside of a window object?)

Question

Is it possible to create a js object that is not under the window object?

(是否可以创建不在window对象下的js对象？)

If yes, then how?

(如果是，那怎么办？)

There is a different ongoing discussion when I'm trying to understand the location of _internalRoot object created by ReactRoot() constructor.

(当我试图了解ReactRoot（）构造函数创建的_internalRoot对象的位置时，有一个正在进行的讨论 。)

Good people say that most probably it's not under the window object.

(好人说，这很可能不在window对象下。)

I was sure that we could not create an object outside of a window object.

(我确定我们无法在window对象之外创建对象。)

Just create the object in a local variable:

(只需在局部变量中创建对象：)

function example() {
    var demo = {};
}
example();

Even if example is a global variable and somehow tied to window , the demo variable is not.

(即使example是全局变量并且以某种方式与window绑定， demo变量也不是。)
