Before we know the difference between Angularjs and Nodejs, it is important to understand a bit of what Angular.js and Node.js are. 

Node.js:

Node.js is a runtime environment, basically an open-source JavaScript for building network applications. The coders execute the code on the server-side, like in a browser or own computer. This means Node.js is scalable, light and a programmer can write code quickly. It allows and integrates app development minus the need to try different languages. Though Node.js is mainly used to build web apps in real time, it is deployed for mobile app development as well. Let us take a look at some of the salient Node.js advantages in real-time app development:

1. Node.js helps you utilize the code or script written in few other languages as well
2. It is quick, scalable and really light allowing the developers to write the code on the server-side i.e., on one’s own PC or directly in a browser
3. Node.js can develop web apps in real time
4. Mobile app developers can use Node.js to good effect

AngularJS:

AngularJS, released in 2009, is one of the most happening frameworks around the web world. AngularJS is a powerful front-end JavaScript framework for developing single page applications (SPAs).

Besides, rich standard library provides a collection of custom extensions.  Another advantage is its huge community and a Core.  

AngularJS is quite popular with its robust framework and open source code for web applications comprising one HTML-pages and CSS JavaScript named SPAs. As a matter of fact, AngularJS is a monolithic framework comprising three paradigms: Models, Controllers and Views, as MVC design pattern is known.  However, Angular developers may say that it has very little to do with MVC, though it looks more like it. Angular JS is particularly great for small and medium projects as it comes with the following benefits: 

1. Big developer community
2. Perfect documentation 
3. 2-Way data binding that further breaks down some processes 
4. Excellent HTML debugging
5. Quick scaffold
6. Excellent for carrying out a lot of unit tests during development
7. Comprehensive solution for your application all the way along

All said and done, there are pros and cons to every single scripting language and framework, which, like it always goes, you need to explore based on what your app build requires; the choice literally is up to you.
