Which one of the below language is best for backend Python (Django) or PHP or node. js

Answer 1

In my opinion, NodeJS is the best for backend development.

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
Also, it is asynchronous, which makes it easier to handle multiple requests at the same time. Further, it is also cross-platform as it was written in C/C++!

Edit:
Bheemashankar, NodeJS is generally used along the MEAN stack, where we have AngularJS (JavaScript) to do the CPU-intensive task. NodeJS is ideal for data-intensive task, not CPU-intensive!

Answer 2

when it comes for the CPU usage it lag's .... that's why I am in confusion
