Python and Node.js are two of the most commonly used technologies used for backend development. Both are known for their advanced features and functionalities, which makes it difficult for product owners to select either technology for their development requirements.
The backend or server side of a particular application is the backbone of every project, with the client side running on it. However responsive your front end is, the application may fall flat without an efficient backend to hold it up. That is why it is necessary to decide between Node JS vs Python for backend requirements.
Node.js vs Python: Understanding The Key Features
Node.js is an open-source, cross-platform JavaScript runtime environment. It is considered to be one of the topmost JavaScript frameworks for web development. Companies hire Node.js developers to work with in-built optimizers, interpreters, and Just-In-Time (JIT) compilers. Most of them run on Google’s powerful V8 engine, which converts JavaScript code into machine code for enhanced speed.
Node.js also helps build real-time data streaming apps, RESTful APIs, microservices, and chat applications, including other web servers. Its asynchronous, event-driven architecture ensures minimal overhead.
Python is an object-oriented, general-purpose programming language that offers a set of libraries and packages to build several web, mobile, and desktop apps. The best part about Python is that it supports many programming standards and is a versatile language used in web development, data analysis, artificial intelligence (AI), machine learning (ML), and scientific computing.
Companies can hire remote Python developers to build scalable applications and automate processes through libraries such as Pandas, NumPy, and TensorFlow
Node.js Vs Python: Know the Differences
Both Node.js and Python are important for ensuring efficient backend development of applications and servers. However, there are some major differences between these technologies that set their functionalities apart. Here’s an overview:
1. Performance and Speed
High performance and speed must be the primary features for all web and mobile apps. No matter what application software you plan to create, these factors can make or break your product.
Node.js
- Node.js can process multiple requests at a time and speeds up code execution with an event-driven, non-blocking I/O architecture.
- Hiring Node.js developers allows you to code outside the web browser with TCP sockets for low-level networking tasks.
- You can cache fetched data with Node.js, which contributes to a higher speed than Python web development.
- NodeJS apps’ performance and responsiveness are excellent for developers running JavaScript codes on the Google-invested V8 engine, which features JIT compilation for faster execution.
- Node.js supports WebAssembly (WASM), allowing developers to integrate other programming languages like C++ into their JavaScript projects.
Python
- Python uses a Global Interpreter Lock (GIL) which processes only one thread at a time, making it slower for concurrent tasks compared to Node.js.
- Python is known for its interpretive nature, which can slow execution compared to compiled technologies.
- Python can be a major letdown if you want a quick recall of data from the server.
- This technology is not the best choice if you prioritize speed and performance in your app using some complex calculations.
2. Scalability
Scalability refers to the linear growth of resources due an increase in application functionalities. This should be the primary factor for choosing your backend language from the beginning.
Node.js
- Node.js frameworks for app development enable non-blocking I/O and asynchronous architecture for better scalability.
- Node.js uses a set of modules and microservices for its functionalities. So, all you need to do is leverage a few modules to make the technology more efficient.
- The technology allows you to scale both vertically and horizontally. This involves adding more clusters or shards to systems and incorporating more resources into the same nodes.
- Node.js supports Load Balancers to handle high-traffic applications.
- Node gives you more options for typing. You can either choose strongly-typed TypeScript or weakly-typed JavaScript for the same purpose.
Python
- Python still uses the Global Interpreter Lock (GIL), which does not support multi-threading and is a major setback for the technology.
- You can increase scalability only with imported libraries in Python, unlike the innate scalability of Node.js.
- Python is dynamically typed and is not an efficient programming language for large-scale projects that usually have more development needs.
- As the Python system grows, it also becomes difficult to maintain it because the technology becomes unnecessarily complex.
3. Architecture
Architecture is another factor to check before you select your backend development technology. It refers to the common approaches or practices to abide by the language or framework.
Node.js
- The input and output of Node.js are asynchronous because it is event-driven and based on an Event Loop mechanism, which avoids thread-based requests.
- Concurrent execution of multiple requests makes Node.js an ideal choice for applications that usually work in real-time.
- Node.js real-time apps like collaborative tools and gaming apps are more responsive and effective.
Python
- Python is more synchronous than other backend technologies, which makes its work slower.
- You may use the Python Asyncio library to run other significant and parallel processes.
- Python’s CPython modules allow developers to convert code into C for performance optimization.
4. Learning Curve and Syntax
A learning curve represents the relationship between how a learner has performed in a task and the amount of time they took to complete the same in the field of software development. Syntax, on the other hand, refers to the ability of a framework or language to run certain functions with as little code as possible.
Node.js
- Anyone who is familiar with JavaScript can run Node.js easily because it is a JavaScript-based environment.
- Node.js also has a low entry limit which means you may come across numerous incompetent developers. However, you can mitigate this problem easily if you know how to hire Node.js developers with efficient experience.
Python
- Python is easier to learn and implement across systems if you do not have any JavaScript knowledge.
- Python often takes fewer code lines to write a particular function. The best part is that these unique codes are easy to read and debug.
- Learning Python can teach your developers how to indent the code accurately because it is a whitespace and indentation-sensitive language.
5. Libraries and Tools
Most websites have lines of code, and developers always want to choose a language with libraries that offer efficient design and development. This helps reduce the burden as code reusability assists in time-efficient development.
Node.js
- NPM is the library and package manager of Node.js. Installing it on Windows and Mac helps you build scalable apps instantly.
- Currently, NPM is the biggest repository on the web with over 350,000 packages.
- Documentation on Node.js helps developers by creating an efficient learning curve for the language.
Python
- PIP (Python Package Index Installer) is the library and package manager associated with Python. Developers often find it faster and easier to work with. PIP offers access to several libraries, extensive documentation, and clean, compact code, making it a favorite among developers.
6. Job Opportunities
Both Node.js and Python provide developers with excellent scope for job opportunities. However, you must know the difference between the Python vs Node.js salary range to understand which option works best for you.
Node.js
- Node.js developers earn an average annual salary of approximately $124,000 in the United States.
- Node.js developers usually have job titles like Full Stack Developer and Software Engineer.
Python
- Python developers earn an average annual salary of around $97,000 in the United States.
- Python developers usually have job titles of Software Engineer, Data Scientist, and Machine Learning Engineer.
