Now, let’s dig deep and analyze Node.js vs Python in-depth.
OVERVIEW OF PYTHON
Python is a high-level, interactive interpreted, object-oriented programming. It is designed in such a way that is highly readable. High-level built-in data structures that are merged with dynamic binding and dynamic typing, which makes it very attractive for developing any application faster.
It is simple and easy to learn syntax readability. the modules, libraries, packages encourage code reuse and program modularity. Often, programmers fall in love with python because it increases your productivity and consumes less time to develop code.
FEATURES OF PYTHON
Python is called a dynamically typed language because of the ease it provides with coding. It comes with many awesome features that will astonish you to your very core. Those features are:
#1 Easy to code:
#2 Object-Oriented Language:
One of the main and most important features of python is; it is object-oriented programming. Being an object-oriented language it supports objects encapsulation, different concepts of classes, etc.
#3 GUI Support:
You can create Graphical User Interface in python using PyQt5, PyQt4, Tk, or wxPython. Out of all four, the most popular and highly used option for a graphical app using python is PyQt5.
#4 Open Source and Free:
It is available for free on its official website. All you have to do is search for the “Download Python”keyword on Google or any search engine of your choice.
Since it is open-source you can access available source codes according to your need.
#5 Python is Portable:
Python Programming is portable. For example, if you have a code you wrote in windows and you wish to run it on another platform like Mac, Linux, or Unix, you will not have to change the whole code for that. You can run that code on any platform.
#6 Interpreted Language:
Python is an Interpreted language because the code in it is executed line by line like C, Java, C++, etc. In this, you don’t have to compile the code. Thus, Python code makes it easier to debug our code. Its source code is translates into bytecode, which is an immediate representation of the code.
#7 Standard Library:
Language comes with a large standard library that offers a useful set of modules and functions so that you’ll not have to write new code every single time. You can directly use the library and save time.
OVERVIEW OF NODE.JS
Node is easy to start with, it comes in use for prototyping and agile development. It also comes in use for building super fast and highly scalable services such as PayPal, Uber, Netflix, Walmart, and many more.
FEATURES OF NODE.JS
Features of node.js make it different from other loved programming languages and make it more popular for faster & awesome back end development. Have a look at the awesome Node.js back end development features:
#1 Asynchronous Programming:
Here, event driven IO supports concurrent request handling. Node.js’ APIs are all offbeat. This component specifies that if a Node receives a request for an Input/Output operation, it will perform that task invisibly while planning other solicitations.
#2 Fast Code Execution:
#3 Highly Scalable and Single-Threaded:
Node.js follows a solitary string model that brings circling of occasion. Node.js follows an event mechanism that can respond by achieving the server very quickly. Since Node.js is non-blocking, all functions (callbacks) go to the event loop, where several threads execute them.
#4 No Buffering:
Applications in Node.js never buff any data. All Applications simply output the data in form of chunks.
DIFFERENCES BETWEEN NODE.JS AND PYTHON:
Architecture is a place to attach to the framework or language with common practice to achieve the desired output. Here, Python follows a common way of implementation known as “CPython” that uses interchangeable code modules. Where Node.js is a single-threaded architecture that handles multiple requests in a single thread.
The difference between the architecture of Node.js vs Python is:
|Node.js is a runtime environment with asynchronous programming on the server-side. It means that some processes will be running while the input-output functionality is not blocked.|
In Node.js, parallel processing can be done such that deploying the application is quick. The event-driven architecture of Node.js allows taking any actions when any event takes place.
|Compared to Node.js, Python provides its opposite functionalities. Python is synchronous and supports single threading. In Python, You have to run and finish one whole process.|
Although, Python does provide libraries like asyncio to make the code asynchronous, using the async/await syntax. asyncio code is an exact fit for high-level and IO-bound structured network code. Where it also provides high-level APIs to perform network IPC and IO; distribution of tasks via queues; keep control over subprocesses; and many more.
asyncio may be a single time saver for you but they cannot make python asynchronous to the full extent. It may happen that you may not achieve the desired asynchronicity.
In this, the heads-up goes to Node.js for having asynchronous architecture.
The scalability of any language makes us clear about how effective the language is during handling huge user traffic and how it can be managed using fewer servers. Scalability is essential in content-heavy applications and those that serve a diverse set of new users through the use of mobile and desktop interfaces.
|Node.js is single-threaded and has an asynchronous architecture that is totally based on events and non-blocking I/O that is used to make most of the computer and CPU memory.|
The asynchronous nature of Node.js makes it more powerful because of its concurrent request execution compared to synchronous/ multi-threaded architecture. In node.js I/O does not block the program execution under I/O heavy workload that helps Node.js application runtime performance all over.
|Python being synchronous in nature and supports coroutines. These coroutines can help you achieve asynchronous processing.|
Python may not seem scalable in nature but it does come with the tools that can help you achieve the desired scalability. Python also weighs well in terms of code complexity, making complex projects easier to code, whereas Node.JS may pose difficulties due to its asynchronous programming.
Libraries gave a new base to the whole scenario of app-development technology in the last few decades. If something has already been developed as a code, there should be no need to recreate it. Instead, you can easily integrate this code from libraries to your code/program at the time of development.
|Node.js is known for its detailed, well-documented, and comprehensive libraries which are managed by Node Package Manager. NPM is called the largest repository in the world because it provides 3,50,000 packages.|
Ain’t that amazing?
|In Python, libraries are managed by pip- ‘Pip Install Packages’ is its acronym. Python libraries are well-documented and easy to deploy. But with the new libraries coming up, it is not well documented as older ones- which makes the new libraries less reliable.|
A group of active/current users that works with the new technology. In these technologies, current developers are responsible to keep updating the popular libraries, add new features, and run debugging programs.
A good community is one that is managed by a single dedicated organization that works for a particular programming language.
|Node.js is not as old as python. It’s true whether you believe it or not. You might consider its community to be strong, but you’d be surprised to know that it has a quite active community of Node.js developers with a large follower base.||Python being the older language has a larger community. The biggest advantage of having a large community and easy to learn syntax is that; you can find the best developer from any corner of the world. A large community means active participation in every python development requirement and these seats are filled by the developers to bring out one happening solution.|
Both languages are very popular and are known for the unique ability they possess to make programming easier. Both of them are open-source and free to use.
Here, you need to make the choice of which language’s functionality will suit your project more.
