What Is The Global Variable In Javascript?

This code: https://github.com/bjornharrtell/jsts/blob/master/index.js refers to a variable named 'GLOBAL'. When I run this in a browser, I get an error message: 'ReferenceError: G

Solution 1:

In Node.js, GLOBAL is an alias to the global object (more commonly referred to as global). In browsers, it doesn't exist.

Browserify recognizes the global alias, and will inject a reference to window, but does not recognize GLOBAL.

It was changed to globalfour years ago

Solution 2:

Global variable came from the implementation of javascript in nodeJS

You can see it as Windows object for implementation of javascript in a web browser

Solution 3:

The code you are looking at is designed to run in a Node.JS environment.

The GLOBAL variable is documented in the node manual.

It is a feature provided by the Node environment and not a core part of JavaScript.
