Python vs Node.js

Each software project has its specifications and requirements. Hence, when you’re developing an application, it’s necessary to select the appropriate technology to code it. Here we will compare Python vs Node.js to explore their advantages, disadvantages, and use cases so that you can select the best technology for your project. Before starting the comparison- Python vs Node.js, let’s have a look at why the selection of technology does matter for your project!

Why Your Tech Stack Choice Matters?

You can approach your companions for recommendations about what technology to select, browse online, or ask developers which technology they prefer. Each source will offer you a different solution, however none of these solutions will let you reliably determine which technology is the best fit for your project. Programming languages and frameworks were intended to fulfill project objectives, and that is the essential criteria for your decision. Try not to go by just popularity. For instance, few technologies are a better fit for Big Data applications (like Python and R), while others are mostly used for building large desktop applications (like Java and C/++/#). Know the best frameworks for building desktop applications at- Best frameworks for desktop application development.

The selection of technology should be deliberate and based on your requirements and capabilities, for example,

  • Project type: business application, game, payment software
  • Product type: a dynamic messenger, or a data analytics platform
  • Application geography: local, countrywide, or worldwide
  • Budget: how much you can spend on technology and developer salaries to build and support your project in the long run

The list can go on, but it’s necessary to consider every feature of your future product when selecting the technology you’ll use to build it. With this comparison, Python vs Node.JS, you will get to know how technologies differ by their advantages and application areas.

What is Python?

Python is an object-oriented, high level, dynamic and multipurpose programming language. Python’s syntax and dynamic typing with interpreted nature, make it a perfect language for scripting. It supports numerous programming patterns, including object-oriented programming, functional programming, and procedural styles. Also, it is an interpreted language that implies it can’t convert to computer-readable code before it runs at runtime.

What is Node.js?

Node.js is a server-side platform built on Google Chrome’s JavaScript Engine. It uses a non-blocking, event-driven I/O model. With Node.js, developers can create data-intensive real-time applications that run across distributed devices. JavaScript is used to write Node.js applications. It can be run on OS X, Microsoft Windows, and Linux operating systems. It is broadly used to run real-time server applications.

Let us see Python vs Node.js.

Python vs Node.JS-

Python vs Node.js

Node.JS isn’t a programming language, but Python is. JavaScript is Python’s language whereas, for JavaScript, Node.JS is a runtime environment. The most essential difference between Python and Node.JS is that you use a similar language for both the backend and frontend when you write in Node.JS. Let us compare both the technologies with different perspective such as speed, performance, architecture, scalability and so on.

1. Architecture

Python-

Python is used for developing event-driven and asynchronous apps using special tools. In Python, modules like asyncio help to write asynchronous code. However, this library is not created in maximum Python frameworks and it needs some extra activities.

Node.JS-

With an event-driven environment, Node.JS allows asynchronous input or output. A particular procedure is called as early as that specific event happens; consequently, no procedure hinders the thread. Node.JS’s event-driven architecture is great for building web games and chat applications.

Node.JS again comes to the first point due to this event-driven architecture.

2. Syntax-

Python-

The syntax of Python is its biggest benefit. When it comes to coding in Python, developers don’t need to write a lot of code lines. Python has simple, easy and also free of curly brackets syntax. Hence code is quite easy to debug and read. Also, python code is easy to read and understand by clients having a technical background.

Node.JS-

Syntax of Node.js is similar to JavaScript of the browser. Hence if you are familiar with Javascript, its easy for you to deal with Node.js.

Here, Python wins because Python’s syntax is easy to learn and understand for beginners.

3. Speed & Performance-

Python-

JavaScript and Python are normally slower than compiled languages like Java, and they are interpreted languages. Python is single-flow, unlike Node.JS, and requests are more slowly processed.

Hence, Python is not a better option for applications that need performance and speed or engage many complex calculations. 

Node.JS-

The performance of Node.JS is remarkable because JavaScript code in Node.JS is interpreted with the V8 engine. Node.JS applies the code outside a website browser. In this manner, the application performs better and is more resource-efficient. Also, this allows you to use features that you can’t use in a browser like TCP socket.

Node.JS features a non-blocking event-driven architecture that allows numerous requests simultaneously, which accelerates code application. And, in Node.JS, single module caching is enabled, which eradicates application loading time and makes web applications more responsive.

Hence, Node.JS web apps are faster than Python web apps.

4. Scalability-

Python-

Python doesn’t support asynchronous programming by default. Hence, the architecture of Python is not scalable. However, Python contains some tools to provide, which helps accomplish scalability seamlessly.

Node.JS-

Scalability is an application’s ability to help a large number of users without any error in its performance. Through Node.JS programming, scalability can be achieved as it builds asynchronous architecture in one thread. This JavaScript framework’s default feature ensures the seamless scalability of the application written in Node.JS code. With the use of Node.js framework, simple and also easy web applications can be developed with complete assurance of scalability. To offer a similar convenience in the complex application, you will require employing Node.JS application developers who have knowledge about this.

Since Node.JS offers easier scalability in comparison with Python, it wins in this case.

5. Learning Curve-

Python-

Python language is not written in a popular language like Node.JS. Hence, its syntax is new to the python developers. It has a compact and cleaner code. An individual can write a code effectively as they don’t have to write more lines of code. In Python, some code lines can assist you reach a similar result as Node.JS. 

Also, as it’s not a new language, it has built documentation properly. Hence, with regards to Python, you won’t run short of knowledge if you are a developer. As indicated by a review of StackOverflow, Python is one of the most favored languages. Full stack developers prefer using this appropriate, simple, and efficient language for application development. Hence, basically, Python is simpler to learn than Node.JS.

Node.JS-

If you know JavaScript, you can easily learn the Node.JS framework. Because of it’s easy to learn feature, Node.JS is on the topmost position in the list of the most popular frameworks with a score of 49%.

6. Error Handling-

Python-

Here, Python takes less time than Node.JS in troubleshooting errors and bugs. Hence error management won’t suffer if you select Python for web development. Also, it will eradicate the complete finishing time and create more possibilities of getting an exclusive website in a single attempt.

Node.JS-

Errors can’t be avoided when you are writing codes. The transparency and feasibility in distinguishing errors are necessary in terms of a programming tool. Node.JS is effective in error management. It has a good command in perceiving exceptions that occurs at the time of code application.

7. Libraries

Python

Pip Installs Python handles packages and libraries in Python. PIP is easy to use, reliable, and quick, so developers find it both easy to learn and work with.

Node.JS

In Node.js, NPM i.e, Node Package Manager handles the packages and libraries. This is a large warehouse of software libraries. NPM is easy to learn, properly documented, and quick for working with.

Thereby, both Python and Node.JS wins in terms of libraries.

8. Community-

Python

Python is an open-sourced and more developed language as compared to Node.JS. It has a large number of experienced contributors. Whether you are a developer or a business owner, you can take advantage of a large community.

Node.JS

Node.JS is an old, open-sourced language. It has an active and large community. It is a most preferable language by developers across the world.
