Node.js is a server-side runtime environment for JavaScript that provides access to resources such as file system and network sockets. Browser JavaScript is a client-side programming language that runs in the browser and interacts with the DOM and web platform APIs. They use different module systems and have different versions of JavaScript support.

How Node.js differs from Browser

In Node.js, modules are reusable pieces of code that can be exported from one program and imported into another program. Globals are variables that are available throughout the entire application. It is generally not recommended to use globals in your code as it can lead to naming conflicts and other issues.

In this video, you will learn about modules and global objects in Node.js. Modules are reusable pieces of code that can be imported and exported using the `require` and `module.exports` functions. You will also learn how to create your own custom modules by defining functions and objects that can be accessed by other applications. Global objects are available in all modules without any imports. Some examples of global objects are `__dirname`, `__filename`, `console`, `process`, and Buffer. Watch this video to master the basics of modules and global objects in Node.js!
