The rise in popularity of JavaScript has resulted in many changes, and the face of web development today is very different. Things we can accomplish on the web now with JavaScript running on the server and in the browser were unthinkable just a few years ago or were encapsulated within sandboxed environments like Flash or Java Applets.

 

What exactly is Node.js?

 

Node.js is a run-time environment for JavaScript on the server. It includes Google’s V8 engine, libuv for cross-platform compatibility, and a core library, all of which are open-source. Because Node.js does not operate in a browser, it does not expose a global “window” object.

 

What is the purpose of Node.js?

 

Because of its single-threaded nature, Node.js is best suited for non-blocking, event-driven servers. It was created with real-time, push-based architectures in mind and is utilized for traditional websites and back-end API applications.

 

What is a web framework?

 

Web frameworks, such as Angular and React, are libraries that aid in the organization and generation of front-end code that runs in a browser. They cut down on development time by reusing code for common tasks. Some web frameworks are “full-stack,” which means they generate both front-end and back-end code for use on a web server.

 

Is Node.js a framework?

 

No, it’s an environment in which back-end frameworks operate. Express.js (or just Express) is a popular HTTP server, while Socket.IO is a popular WebSocket server.

 

Is Node.js considered to be a programming language?

 

No, the “.js” stands for JavaScript, which is the programming language used by Node.js (or anything that can transpile to it, like TypeScript, Haxe, or CoffeeScript.)

 

Why is Node.js popular?

 

Apart from being good at what it does, Node.js is well-known for its large, active, open-source, JavaScript-based ecosystem. It also doesn’t likely to cause serious compatibility issues across versions.
What is the difference between Node.js and Angular/AngularJS?
Angular is a JavaScript framework that is executed on the client, whereas Node.js executes JavaScript code in its environment on the server (i.e. within a web browser.)

 

What makes Node.js so bad?

 

Due to its single-threaded nature, Node.js may be a poor fit for web servers that also serve as computational servers, as intensive processing will stifle the server’s responsiveness. Node.js, on the other hand, isn’t all bad: The technology is well-established and widely used in a variety of server configurations.
