Python vs JavaScript: Key Differences You Must Be Aware Of

Python and JavaScript are the two primary languages that are most popular and powerful, but they do have key differences.

To understand that specific differences, we’ve come up with an article that depicts the difference between Python vs JavaScript. You’ll come across the basics of Python & JavaScript before we deep dive into their differences.

What is Python?

Python is a high-level object-oriented programming language that is an ideal choice for rapid application development. With its built-in data structures and dynamic binding functionality, Python occupied the fourth position in the list of most used programming languages among developers.

If I talk about the top features of Python, the list is huge. However, let’s highlight the prime features of Python Programming language.

  • Easily build web-based servers and applications.
  • It’s the perfect solution for shaping data-driven solutions.
  • Python uses custom runtime patterns to enhance the application speed.
  • Python is a completely open-source platform.
  • It’s entirely compatible with leading platforms, databases, products, and programs.

What is JavaScript?

JavaScript is a scripting or programming language that makes it easy for businesses to implement complex features on web pages smoothly. In simple words, I can say that for every web page visit, it does more than simply displaying static information for you.

What you can do with JavaScript?

  • Displaying timely content updates
  • Creates interactive maps
  • Performs animated 2D/3D graphics
  • Scrolling video jukeboxes and many more

With its lightweight feature, JavaScript allows you to create more dynamic interactions when developing web pages, applications, servers, and or even games.

However, you can efficiently use JavaScript alongside HTML and CSS to make your business application more responsive. With the help of JavaScript, implementation of web, mobile application, and game development is much more easier.

Python vs JavaScript: Detailed Comparison

After looking at the basics of Python and Javascript, it’s high time to highlight the difference between Python VS JavaScript in various terminologies.

JavaScript Is Best In Terms of Speed & Performance

Python is a programming language that is well-known for its CPU-intensive tasks. On the other hand, JavaScript works the best for creating dynamic and real-time interactions.

JavaScript is solely responsible for enhancing the  speed of business application and also plays a vital role in improving user engagement. And it is made possible with the help of Node.js framework. 

And if you ask me which is faster: Python or JavaScript? JavaScript wins the battle in terms of application speed and performance. The below figure depicts the performance outage for both Python vs JavaScript.

Difference between Python & JavaScript

And if I talk about Python, its the best for processing huge data files, CPU-intensive projects, and large-scale applications. And if you’re using Cython or NumPy tools for performing code optimization, it will definitely provide you with the best application performance.

Python Has Gained Huge Popularity

As we are comparing the two big back-end technologies, Python and JavaScript are popular one for developers and business owners. In terms of popularity, both technologies are the best, but to be precise, Python is the winner.

As per the recent survey by Statista, JavaScript has occupied the 4th position in the most commonly used programming language.

Python app development is usually fluctuating with lot of ups and down. And according to the TIOBE Programming Community Index 2022, Python has secured the top position, beating Java, C, and JavaScript.

Apps Developed With JavaScript Language are More Scalable

JavaScript is a programming language that typically supports multithreading features, while Python is a language that allows you to deal with only a single thread at a time.

If you want to build an application for your business that scales well, you should move ahead with Node.js development services. The primary reason behind it is that it is built specifically on JavaScript language. 

Simply put, the applications developed with JavaScript allow you to easily increase the number of threads and scale apps as and when needed. On the other hand, Python actively uses GIL (Global Interpreter Lock), which does not include concurrent programming support.

Moreover, Python makes it challenging to utilize multiple processors with threads. This simply states that application scaling works best for JavaScript programming language.

JavaScript Has a Steeper Learning Curve

JavaScript is one such programming language that is usually not easy to learn, and thereby I can surely say that it supports a steeper learning curve. But, it’s not the same case with Python language.

In fact, Python is a developer-friendly language and very easy to grasp for any developer.

Quote on Python

Here, we are talking about the difference between Python and JavaScript; many freshers typically prefer Python as their primary language. Some of the reasons are minimized structural lines, readable & maintainable code, and, most importantly, a quicker development process.

Python Is Built With Feature-Rich Modules & Libraries

Python is a feature-rich and innovative platform that possesses a bundle of modules and libraries. JavaScript does not have many such libraries and modules except a few, like JSON and Math.

Inside the Python language, you’ll find a list of components that enables you to deal with innovative Machine Learning, Data Analytics, and even scientific applications. So, you can just imagine the power of Python programming language. 

And if I talk about JavaScript, only a few pre-configured modules exist. So, this is the major difference between Python vs JavaScript.

JavaScript Makes Web & Mobile App Development Process Smoother

If you’re using JavaScript to develop web and mobile applications for your business needs, you’re on the right path. JavaScript helps you perform code faster, work quickly, and, yes, manage a large bunch of data.

Compared to JavaScript, Python usually takes more time for web & mobile app development. With its asynchronous nature, JavaScript plays a vital role in offering high-end scalability to business applications to a great extent.

It does not mean that Python is not a good option for application development. Python is essential as it is solely responsible for dealing with server-side development. 

However, it provides a stable development environment with leading frameworks like Django, Pyramid, Flask, and many more.

Python VS JavaScript:  The Comparison Table

Python is a high-level programming language that is object-oriented.JS, or Javascript, is a scripting language.
Guido van Rossum is the man behind the invention of Python.JavaScript was created by Brendan Eich (Netscape), currently maintained by ECMA.
Python is a programming language that is easy to read and maintain code.JavaScript is completely flexible and so it does not provide easy code readability or code maintainability functionality.
An interpreter is needed to run Python code.You just need the browser to run Javascript codes.
Python is a dynamically typed language.JavaScript is a dynamically typed language as well.
Python is best used for server-side scripting.JavaScript is commonly used for client-side scripting.
By default, Python is encoded as ASCII language.JavaScript supports UTF-16 encoding.

Python VS JavaScript: Whose the Ultimate Winner?

If I talk about the winner, comparing these two leading technologies cannot be done as it would not be fair enough. Python and JavaScript are inspiring backend technologies but are meant for different perspectives.

Both technologies have their own predictive use cases that make the development process smoother and more efficient. 

The distinctions between Python and JavaScript enable them to complement each other seamlessly in the software development lifecycle.

To be precise, JavaScript rules the world for mobile and web app development, while Python rules the ML market for its ease of use and ability to perform data manipulation.
