 - Code running in a {{domxref("Worker")}} has a {{domxref("WorkerGlobalScope")}} object as its global object.
 - Scripts running under {{Glossary("Node.js")}} have an object called [`global`](https://nodejs.org/api/globals.html#globals_global) as their global object.
 
-> **Note**: Unlike {{jsxref("Statements/var", "var")}}, the statements {{jsxref("Statements/let", "let")}} and {{jsxref("Statements/const", "const")}} do not create properties of the global object.
+The [`globalThis`](/en-US/docs/Web/JavaScript/Reference/Global_Objects/globalThis) global property allows one to access the global object regardless of the current environment.

+[`var`](/en-US/docs/Web/JavaScript/Reference/Statements/var) statements and [function declarations](/en-US/docs/Web/JavaScript/Reference/Statements/function) at the top level create properties of the global object. On the other hand, {{jsxref("Statements/let", "let")}} and {{jsxref("Statements/const", "const")}} declarations never create properties of the global object.
 
-The `window` object is the Global Object in the Browser. Any Global Variables or Functions can be accessed as _properties_ of the `window` object.
-
-### Access Global Variables
-
-```js
-var foo = "foobar";
-foo === window.foo; // Returns: true
-```
-
-After defining a Global Variable `foo`, we can access its value directly from the `window` object, by using the variable name `foo` as a property name of the Global Object `window.foo`.
-
-#### Explanation:
-
-The global variable `foo` was stored in the `window` object, like this:
-
-```js
-foo: "foobar"
-```
-
-### Access Global Functions
-
-```js
-function greeting() {
-   console.log("Hi!");
-}
-
-window.greeting(); // It is the same as the normal invoking: greeting();
-```
-
-The example above explains how Global Functions are stored as _properties_ in the `window` object. We created a Global Function called `greeting`, then invoked it using the `window` object.
-
-#### Explanation:
-
-The global function `greeting` was stored in the `window` object, like this:
-
-```js
-greeting: function greeting() {
-   console.log("Hi!");
-}
-```
+The properties of the global object are automatically added to the {{glossary("global scope")}}.
