1. Barrier to entry for professionals
With Python, the situation is different. For example, our Python developers for remote teams proactively create solutions with Python using simple libs that are easier to learn than JS libraries. Thus, a lot of utilities, data scrapers, and network applications can be created in a matter of hours.
2. Application domains in software development
Performance depends on many factors and cannot be simply regarded in terms of the language limits. It is important to understand that development and correction speed are more important than performance. Overall, Python is a “slow” language for backend as compared to Node.js.
The event-driven architecture and non-blocking input/output of Node.js allows to maximize computer and CPU usage despite its single-threading. This type of architecture is based on asynchronous calls, which enables Node.js servers to handle more concurrent requests as compared to multi-threaded servers.
Python requires a considerably larger amount of resources, which often implies investing in costly equipment. However, due to the fact that the hardware price is gradually going down and software engineers’ salaries are rising, a lot of applications are written in Python.
Python does not support asynchronous programming, but it does support coroutines that allow to make asynchronous processing. Node.js creates a single-thread asynchronous architecture with input/output not blocking the thread.
Django fans claim it to be an exceedingly scalable framework. Many IT experts doubt this statement. However, there are many facts proving that Django can “digest” tons of traffic. Just have a look at these web applications written in Python:
- Instagram: What Powers Instagram: Hundreds of Instances, Dozens of Technologies.
- Pinterest: Alexa rank 37 and 70 Million users in 2013.
- Bitbucket: 200TB of Code and 2.500.000 Users.
- Disqus: Serving 400 million people with Python.
It looks like Node.js is not willing to step back and keeps evolving. In a few years, we will probably see Node.js applications that yield the same number of users.
