What is the difference between Node.js vs. Python

For back-end development, Node.js and even Python are the most exclusive technologies. There is no specific good or even bad programming language, but the developers’ choice will make the difference of choice at times. So now, let’s dive deep into the two programming languages and get the details of everything.

Overview of NodeJS and Python

NodeJS is more than an open-source runtime environment; it is not a programming language. Ryan Dahl was the one who initially introduced this language in the year 2009. The latest version of NodeJS 12.6.0 gets the release date in July 2019. It is a great thing and depends on the Google V8 engine, and it is a virtual machine with built-in compilers, interpreters, and even optimizers. Google design wrote it in C++, and you will mostly see the use in Google Chrome. Compiling the engine purpose will offer the machine code function of JavaScript. V8 is perfect for high-speed and even advanced regular performances. 

Python is a high-level programming language with an open-source format that was released in 1991. The latest version will be 3.8, released in the year 2019 in October, but if you consider it, you will know that 3.7 is more effective and even popular. It mostly runs in Google’s App engine.

The architecture of NodeJS and Python

Node.js is a perfect event-driven for the environment, which will enable the input and the output. There is a specific process where the respective event will occur, and there is no way that the blocking process of the thread. The event-driven architecture of Node.JS will be suitable for chat applications and web games. 

Python design is a bit different. You can get the most of the unique tools that event-driven apps. The library design is not designed in the Python framework and even requires some additional hustle. The event-driven architecture will bring Node.JS as its first point.

Speed of NodeJS and Python 

As it has an interpretation of the V8 engine, you can check that Node.js and its performances are remarkable. Node.js will execute the perfect code to the outside of the web browser. The app is more resourceful and efficient, which will perform better. This allows you to use features you cannot use in the browser, such as the TCP sockets. The architecture is event-driven and even non-blocking, which will enable several requests and can process during the same time. It even accelerated the code extensions. It is finally a single module caching that will help Node.js and even reduce the loading time app and make it perfectly responsive. 

JavaScript and Python are the interpretation language. They are even slower than the compilation languages the Javs. In this case, Python will beat Node.js. Python is in request and single-flow, and they even process slowly. In the matter of Python, if you Hire web developer India, then you will say that Python is not the right one for performance and speed. It has many complex calculations. Compared to Node.js, Python web application is slow.

Syntax of NodeJS and Python

The syntax is a part of personal preferences. The syntax of Node.js is quite similar to that of JavaScript. So if the developers know about JavaScript, they will not face any issues with Node.js. Python will get the most effective advantage, and in coding, Python and the software developers will need to write a few lines of the code and even fit the coding in Node.js. However, the Python syntax is still accessible and free from curly brackets. Hence, the code is easily readable and even easy to debug. Clients also understand the code if they have a bit of technical background. It depends on personal preferences. It depends on your personal preferences and gives you a better result. 

Scalability of NodeJS and Python

For Node.js, you will create a monolithic core in extensive form. There is a set of microservices and even different modules. There are modules; all will communicate with the lightweight mechanism and even run down to the process. There is an easy and even extra module and microservices, which makes the development process flexible. Node.js web app will quickly scale to the web app vertically and horizontally ways. If you want to scale horizontally, you can add new system nodes that you can have. If you’re going to scale vertically, then you can add those nodes with extra resources that you can have. In terms of typing, you will get more options in Node.js compared to Python. You can use JavaScript weakly-typed and the TypeScript strong-type. 

In Python, app scalability and multi-threading need a perfect enable option, and Python will not support multi-threading because of GIL, I.e., Global Interpreter Lock. Python opts for multi-threading limbs, and they are not accurate in multi-threading. GIL will not allow the Python interpreter to perform the task and does not make it one thread at a time run. Python will use the GIL though it can negatively affect performance because it has memory management of Python, which is not safe for the thread. Python is not a dynamically typed language and unsuitable for large projects and growing development teams. When it grows, the system will gradually become complex and even difficult to maintain. 

Extensibility Node.JS and Python

The developers can customize, integrate, and extend with different tools and open it with built-in APIs to develop HTTP and DNS servers. One can combine it with Babel, facilitating the front-end development with definite Node and its old browser versions. Talking about jasmine, it is excellent for unit-testing, and even log.io will be helpful to the project monitoring and troubleshooting g. For data migration, process management, and even module bundling, you can use Wrbpavk, Migrate, and PM2. Even Node.js can get an extension with frameworks like Koa, Hapi, Restify, and others.

In 1991, Python came into the picture, and then many development tools and framework creation were there. Python integration is possible with Sublime text and even offers many editing features with syntax extensions. For test automation, there is Robot Framework. There is even robust web development like, for example,eFlask, Pyramid, Django, CherryPy, and Web2Py. Therefore, both are extensible and even have a winning point. 

Libraries of Node.js and Python

NPM manages the packages and libraries of Node.js. NPM is the Node a Package Manager and the most extensive repository of the software libraries. It is fast, easy to learn, and well documented. Python gets the management with Pip through libraries and the packages. So Pip is reliable, easy to use, and fast, and even you can hire dedicated developers in India to get the best work of the application in a better way.

The universality of NodeJS and Python

Node.js is the one used for the back-end development of web applications. Yet, with front-end development, one can use JavaScript with back-end and front-end and even share the same programming language. With the help of Node.js, you can develop web apps and provide desktops with hybrid mobile apps that come with IoT and cloud solutions. Node.js is also a cross-platform language that the developer can create with a single desktop application that will work on the Mac, Windows, and Linux. The universality of a great way is to reduce cost because only one team of developers can perform it.

On the other hand, Python is full-stack, and you can use it both in front-end and back-end development. It is similar to Node.js, and even Python is cross-platform, and hence Python program is available on the Mac, and one can run it on Linux. Both Linux and Mac have an installation of Python, but on Windows, you need the structure of the Python interpreter. While Python is perfect for desktop and web development, it is even weak compared to mobile computing. The mobile applications are not there in Python, and even for AI and IoT solutions, Python’s popularity proliferates.

The learning curve in Node.js and Python

Node.js is JavaScript, and beginner developers can use it effectively. If you know JavaScript, then you can quickly master Node.js. Installation of Node.js is simple and offers outstanding performance. If you have no idea of JavaScript, then it is better that you choose Python. It is easy to learn, and the syntax is compact and accessible. For example, writing a function on Python will take a few codes line compared to Node.js. 


Which is the best? Both the technology and advance features are good in their journey. But which one promises depends on the choice of the developers and the clients. Each programming language has its benefits, flaws, and needs. Therefore, one should choose the smart one over the other based on the project requirement. The developers know the insight of both languages and the projected trend. They choose the language despite the benefits and flaws in each programming language. You must have a detailed discussion with the developer to know who is the best and who will give you a better understanding of the project to work on the exact framework.
