The compilation of code by the machine is very fast when compared with other competitors. Review collected by and hosted on G2.com.

Not everyone uses the same runtime environment, and the requirements are not always NodeJS for JavaScript. There are so many modules and tools that do not perform well. When performing CPU-specific tasks, NodeJS does not help and is not suited. One must learn the command line syntaxes to use this application. Review collected by and hosted on G2.com.

I like the element that we can coordinate Node.js with various administrations to accomplish the ideal result. We can utilize express just as MongoDB with node.js to get a total bundle for backend improvement. Review collected by and hosted on G2.com.

I can use JavaScript at server side, isn't it the best? Asynchronous event-driven input/output helps concurrent request handling with a single thread. It's fast, easy to implement, and moreover, it's in JavaScript, which means a frontend developer can now write backend code. That's amazing! Review collected by and hosted on G2.com.

We don't have scalability here on the server side; we have to go with other tools, like Kubernetes and Docker. It is not suited for CPU-intensive tasks; hardware integrations are much more complicated. Using it with a relational database could be worse because of a hell of nested promises.
