The JavaScript does not have a well equipped and robust library system in comparison to other programming languages.
The result is that the users are forced to take the support of common library for executing various tasks such as Object-Relational Mapping (ORM), processing of the images, handling database operations, and XML parsing etc.
One of the key problems that most of the developers encounter is the Application Programming Interface (API) keeps on changing at frequent intervals and does not remain stable.
At times, a new API appears having a number of backwards-incompatible changes. As a result the developers are forced to make changes in the accessible code bases to match the compatibility with the latest version of the Node.js API.
The Node.js is known to be highly extensible, which means that you can customize and further extend Node.js as per their requirements.
You can also make use of JSON to provide the scope for exchange of data between the web server and the client. It also is facilitated with built-in APIs for developing HTTP, TCP, and DNS etc. servers.
Since the Node.js is providing the option of non-blocking I/O systems, it relatively helps you to process several requests concurrently.
The system can handle the concurrent request handling efficiently better than others including Ruby or Python. The incoming requests get lined up and are executed quickly and systematically.

With Node.js, the developers can get an extended support for the various commonly used tools. Let’s take an example. Suppose, you want to test the source code of Node.js application; you can do so by using the Jasmin and other such unit-testing tools.
Similarly, if you want to identify and install the project dependencies, you can make use of npm, a powerful package manager. You can use grunt for task running of the project.
Another advantage that Node.js offers to the developers is the freedom to develop the apps and software.
This is one essential feature, which remains absent in Ruby on Rails imposing certain guidelines. You can begin everything from the scratch while developing applications.
The open-source runtime environment of the Node.js also provides the facility of caching single modules. Whenever there is any request for the first module, it gets cached in the application memory.
The developers don’t have to re-execute the codes as caching allows applications to load the web pages faster and responds more swiftly to the user.
Node.js is blessed to have a large and active community of developers who keep on continuously contributing towards its further development and improvement.
In fact, the groups of developers are well supported by the JavaScript programmers providing ready-made and easy solutions and codes in GitHub. It is expected that the developers will initiate many further developers in the future.
It has been mentioned earlier that Node.js interprets the JavaScript code via Google’s V8 JavaScript engine. This engine complies the JavaScript code directly into the machine code. This makes it easier and faster to implement the code in a effective manner.
The speed of the code execution also enhanced by runtime environment as it supports the non-blocking I/O operations.
