1) AngularJS
It is a platform launched by Google in 2009. With this, it is easy to solve the problems encountered while creating a single page application. Why Angular JS is Considered:
- AngularJS uses HTML to define the UI of a web application. This simplifies the entire web development process by defining exactly what you want.
- Web application development is flexible through the use of instructions and filters that expand the functionality of HTML, while filters take care of changing the data.
- Unit testing done in Angular JS is by inserting some dummy data and then measuring the entire output. This is bogus data and then output measurement.
Advantages of using AngularJS
- Large Angular libraries
- Simple routing
- Easy framework to test
- Data binding
- It provides robust templating solutions
Drawbacks
- Limited Routing
- Scopes are difficult to debug
- Third party integration is complex
- As more elements are added, the page slows down
2) ReactJS
ReactJS is an open source JavaScript library that helps improve performance. The model relies on the "presentation" aspect of the View Controller (MVC) architecture, which was created to solve the rendering problems of large datasets in a JavaScript framework. Why ReactJS is considered:
- ReactJS can easily run on servers with virtual DOM rendering, making it easier to make the site more SEO friendly.
- It runs on its own virtual DOM and takes care of all changes or updates to the DOM.
Advantages of using ReactJS
- Get easily updated
- Codes can be re-used
- Component based architecture
- Easy to learn API’s & smooth UI
Drawbacks
- Limitations of integrating ReactJS into MVC framework
- Has always been known as a library rather than a framework.
3) NodeJS
Node JS, as we all know, is a server, not a framework, which is used to facilitate the development of complex applications. Why NodeJS is Considered:
- NodeJS can handle multiple connections easily as it is used as a server side proxy.
The NodeJS library executes code quickly. - JS comes with HTTP, SSL, compression, file system access, and raw TCP and UDP-related working connectors and libraries.
- JavaScript, which is already configured for the web browser event loop framework for GUI and network events, is a great language to connect these connectors.
- Node Package Manager is included in Node.js and has evolved into a repository of around 50,000 packages, so it's possible that another developer has already put together a solution to your problem, or some less common ones as well.
Advantages of NodeJS
- Based on Google Chrome's V8 JavaScript engine, Node.js is efficient and fast at code execution.
- No Buffering
- Single threaded but highly scalable
- Large files can be streamed easily
- Simple to learn
Drawbacks
- Doesn't scale because a single processor is not enough for multiple tasks.
- In-depth knowledge of JavaScript is required to work with Node JS.
- It is primarily intended for web servers and is not intended for CPU-bound tasks, that is, daily tasks or applications that are in continuous use.
Conclusion:
All the above JavaScript frameworks are used all over the world. With advanced technology, it is expected that they will always be the best. With ReactJS, you can reuse code, and it also makes you write less code and do more. AngularJS is a framework and ReactJS is a library. NodeJS is designed to build really fast and responsive applications. Now that we know the difference between these three latest technologies, we can easily determine which web application is best for this purpose.
