One of the key disadvantages of Node Js is repeated API switch that creates back-end incompatibility. This incompatibility directly affects the changes in codes that make it more unstable. Keep these results in mind when choosing Python vs JavaScript for web development.

Node.js vs Python: Which One is Best for Your Project?

Python’s natural architecture restricts multithreading, as a result, creates problems in this aspect too. Till now, we have discussed both the technologies in detail with their several features, benefits, and drawbacks. Multi-paradigm- Python supports object-oriented programming as well as functional and structured programming. Node.js is the perfect framework for microservice architecture, and big companies like Netflix and PayPal have already leveraged it to shift from the monolith to microservices.

Is NodeJS better than Python

Even if you have multiple threads, GIL does not let the Python interpreter perform tasks simultaneously but rather makes it run only one thread at a time. Python has to use GIL even though it negatively affects performance because Python’s memory management is not thread-safe. Second, Node.js executes the code outside the web browser, so the app is more resource-efficient and performs better. This also allows you to use features that cannot be used in a browser, such as TCP sockets. There is no buffering in Node.js as applications output the data in pieces. Node.Js is best suited for small projects, while Python is best suited for developing large projects.

What is Backend Development?

Then, the non-blocking event-driven architecture of Node.js allows processing several requests simultaneously, accelerating the code execution. Node.js includes a few features that guarantee the speed of an application. First, it uses Google’s V8 engine to interpret JavaScript code resulting in a remarkable performance. On the contrary, Python is a naturally synchronous programming language.

Is NodeJS better than Python

The performance of Node.js is hence high, and in terms of speed, people can choose Node.js. So, features of Python do not suit speed, so in terms of speed and performance, Python fails. These criteria are best to choose the correct programming language, and hence people can get to know the basic details of programming by reading the requirements. Node.js is a precise runtime environment that can maintain the connection between the server and browser side so people can enjoy uninterrupted services.

NodeJS vs Python: The Better Backend Technology

One of the most trusted and highly preferred professional social networking platforms that have chosen Node Js to increase the performance of applications. But you also should remember that each software project has its own needs and requirements and you should choose your technology based on those needs. Python is somewhat older than Node.js, and it is also open-sourced. The user community has an immense number of contributors with different levels of experience. Once again, should you be a business owner or a developer, you benefit from the large community.

Whenever the multiple callback situation occurs, it decreases code quality and becomes hard to solve and maintain. According to Upwork, the average hourly rate of Python developers is around $20-$40. I would also like to say thank you to Yaryna Korduba, one of the awesomest web developers at KeenEthics, for inspiring and contributing to the article. Usually, writing a certain function in Python will take fewer lines of code than writing the same function in Node.js. But this is not always the case because the length of your code greatly depends on your programming style and paradigm.

Node.js vs python speed comparison is a common topic of discussion. If you are having a question about that is node js faster than python, the answer is yes. Node.js is best suited for applications that require a constant connection among various servers and browsers, which makes it ideal for chatting or messaging applications. By comparing both the languages we get to know that Node js is better in speed and performance and turns out to be highly useful for heavy-load applications.

Is NodeJS better than Python

Maintainable- As both front-end and back-end use Javascript, Node.js is a common choice among developers. Since selecting the best technology stack is imperative, It can be challenging to choose between Node.js vs. Python- two of the most popular back-end technologies. If you’re working on a project that requires a lot of processing or is data-heavy, then using Python may be the better option. When it comes to Node.js, you might have difficulty finding errors in your code.

Learning Curve

Python’s portability across platforms has earned it the label of “universal programming language.” Python is cross-platform, meaning it can run on any operating system. This includes Linux, Windows, and Mac OS X. Python’s simple syntax also implies that programmes written in it are shorter than those written in Nodejs or even Java. Python, fortunately, is an easy language with which to write programmes. Common operations are married to built-in functions to get the desired syntax. In other words, the more straightforward the grammar, the less steep the learning curve will be. Because of its event-driven I/O API, Nodejs development can gracefully manage a large number of concurrent activities while being relatively lightweight and efficient.

As Python can’t run processes parallel, it slows down the processing speed. Though its syntax is comparatively easy to learn, it isn’t fast enough to recall data from a web server. One of the biggest USPs of Python has been its universality and easy syntax. This fact is known industry-wide that Python’s code length is relatively smaller than Node.js or other prominent programming languages. The package manager of Node.js contains multiple open-source Javascript plugins. NPM has more than 840,000 libraries, and the developers use these NPM modules in over 97% of the web applications.

  • Any application that can be written in JavaScript will eventually be written in JavaScript”.
  • Yet, dynamically-typed languages are not suitable for large projects with growing development teams.
  • To construct interactive websites, programmers turn to Python, an Object-Oriented Language.
  • It allows transforming and manipulating a large number of images at once and extracting useful insights from them.
  • One of the most trusted and highly preferred professional social networking platforms that have chosen Node Js to increase the performance of applications.
  • While Django may help handle high loads, it is not a good option for mobile applications.

Therefore, it requires special libraries such as Asyncio to become asynchronous. Python is easier to learn due to its compact and straightforward syntax. You will require fewer lines of code for writing a specific function in Python than writing the same role in Node.js.


Python has an extensive standard library, making it ideal for performing complex operations without writing much code. The presence of robust data structures gives it an edge over other technologies. Both Node.js and Python middle node.js developer job are easy to learn and settle errors efficiently. Node.js supports callback, and its coding is based on callback or event that makes it process quicker. Python is not precisely the best choice for asynchronous programming.

In my opinion, both NodeJS and Python are great tools for backend solutions. They can be integrated with numerous tools and other languages, which means you can collect a complete toolset to develop any project you need. It’s not recommended to use NodeJS for large-scale web apps because of its problematic scalability and complicated ecosystem. Python, with its concise code and scalability, is ideal for large projects. Python is more widely used for backend development, while Node.js focuses on web applications. Secondly, Node.js and Python can both be used for desktop, web and mobile solutions, although, as we’ve mentioned before, Python is not the best choice for mobile development.

Before getting to the in-depth comparison of Node.js vs. PHP vs. Python, let’s first have a look at a quick overview of each technology. This will help you understand key differences between each technology. Today, coming up with a game-changing app idea for your web application is just half the battle.

What is Design Thinking, and Key Principles Of Design Thinking Process

It was developed to provide high readability, scalability, and fast development. Node Js and Python are the two popular backend frameworks for web app development. Since both of these frameworks are gaining popularity, it gets difficult for product owners to choose the right framework between Node or Python for their product.

Scalability is the vertical growth in the resource needs when you scale your web application. You will have a light web application in the initial stage, and any coding environment can work for the task. Having a simple and highly conversational syntax, The codes written in Python are highly readable. Extensible- As Python is highly versatile, it enables easy integration with C, C++, Java, and other languages.

Modules like asyncio make it possible to write asynchronous code in Python as it would be done in Node.js. But this library is not built in most Python frameworks, and it requires some additional hustle. Comparing Python vs Node.js, Python features consistency, stability, and easiness of use. It is highly preferred for developing scientific applications, big data solutions, and government projects. Machine learning, Crypto technology, Blockchain development, Secure app development, very fast RESTful API development, and many more. I totally agree with you that Python is not the best choice for frontend development.
