what is defference between console.log(this) in nodejs and console.log(this) in browser?

Question

When I log (this) in the browser I get window Object, But when I log (this) in node.js I got {}. I road global object in node js is same window object in browser, What is precisely the deference between this and global Object in Node.js? Thanks for your answers.

Answer 1

Node.js is capable of printing objects without the need to convert them into strings in the console log, while i am guessing in the browser that is not possible. "{}" is an empty object in javascript

Answer 2

Simple answer to me seems to be, in both examples this is the global object for the JavaScript runtime.

• In the browser, this is the Browser Object Model

  • https://www.w3schools.com/js/js_window.asp
  • "All global JavaScript objects, functions, and variables automatically become members of the window object."
  • It is a collection of properties and methods that contain information about the browser and computer screen.
  • Even the document object (of the HTML DOM) is a property of the window object.

• The difference is in the top-level code in a Node module, this is equivalent to module.exports. That's the empty object you see.

  • Meaning of "this" in node.js modules and functions)
  • you would need a library called jsdom in Node.js to get access to the APIs used in a browser DOM https://www.npmjs.com/package/jsdom
