Advantages of Node.js
- Easy scalability
- Easy Nature
- Single Programming Language
- Fullstack JS
- High-Performance Delivered
- Advantage of Caching
Due to its open-source runtime environment, Node.js provides the facility of caching modules. In this way, whenever there is a need for the first module, it is cached in the application memory. This helps the developers to load web pages faster and respond more quickly to commands, without having to re-execute codes.
- Develop apps of your choice
Unlike Ruby and Rails which impose several guidelines and restrictions, Node.js allows you to develop apps and software as you wish. The choice of creating something new remains with you and so does the freedom of building anything from scratch.
- Support for commonly used tools
While using Node.js, developers get extended support for the most commonly used tools. If you wish to test the source code of Node.js application, you can do it with the help of Jasmin or similar other unit-testing tools. Similarly, if you wish to identify or install project dependencies, you may utilize npm- a popular package manager software. You get to use grunt for task running of the project.
Disadvantages of Node.js
- Unstable API interface
The most important difficulty posed by Node.js is that the application programming interface (API) is not that stable. It continuously changes. There are times when a new API with backwards-incompatible changes surface and developers are compelled to change the accessible code bases to match with the latest Node.js API version.
- Absence of a good library
It is not equipped with a well-stacked library as compared to other programming languages. Hence users are forced to rely upon a common library for executing tasks like Object-Relational Mapping (ORM), image processing, handling database operations etc.
- Asynchronous Programming Model
Node.js is an asynchronous programming model and that makes it very scalable (as mentioned before) . However, compared to the linear blocking I/O programming, most developers find the Node.js programming model more difficult.
Inspite of a few hitches, the Node.js comes in more handy than most other programming languages. It’s biggest pro is that it can be used for front-end as well as back-end servers. Business organizations and enterprises have to come rely on Node.js over time with positive feedback and enhanced results.
