Python vs. Javascript for Web Development: Overview

Python vs. JavaScript is a popular term you are likely to hear among developers new to web development. These computer programming languages have similar and varying features that make them useful for Web development projects. This is why so many companies use them while creating their websites.

But in regards to Python vs. Javascript for Web development, you can utilize either as both are versatile, functional, object-oriented, and interpretive.

But one thing you must not overlook is that the founders of these languages had a purpose for designing each language. So in the context of this article, which is about the best language to learn for web development, we will explain each in detail. 

You will learn more about Python vs. JavaScript in this article, including their features, key distinctions, and advantages for Web development.

Python vs. Javascript: Understanding the Two Popular Programming Languages for Web Development 


A Dutchman by the name of Guido van Rossum invented the computer language Python in the 1980s. Python is a high-level, less verbose language that is great for novices since they can use it for scripting, web scraping, and building data sets.

Python’s syntax simplicity is significant to newcomers. Every aspect of software development, including machine learning and data science, can be done with Python. You can use it for text editing, website development, video game development, and artificial intelligence.

Python is the best programming language for building websites because it enables database communication and the sending and receiving of web requests. Some of the most popular websites use it because of this. These include the NASA website, YouTube, Google search, Dropbox, Yahoo Maps, Pinterest, Instagram, and Quora. Since Python is a general-purpose language, learning it will help you develop other applications besides websites.

Among developers, Python is the second-most popular programming language.


In 1995, another well-known programming language, JavaScript, was created by Brendan Eich, a developer at Netscape. For beginners who wish to work as front-end or back-end developers, it’s a fantastic alternative. With the aid of this language, you can build websites right away, which is a valuable skill in the job market nowadays!

The most common host environments in which JavaScript can be used as a programming language are browsers. You can use JavaScript to build both the front and back end of your website since it is a dynamic, multi-paradigm language with standardized built-in objects and functions.

JavaScript has been the most popular programming language for the last nine years.

Python vs. Javascript for Web Development: Features 

  1. Language Simplicity

Beginners are frequently curious about the ease of learning Python vs. JavaScript. Each language is fundamental in its own way. But Python is frequently the preferred language for beginners, particularly those without prior programming experience. Furthermore, according to experts, Python is said to be more readable and easier to understand.

In comparison to other languages like C or C++, Python has fewer structural rules. Other languages have some mandatory rules that Python does not have; using a semicolon after each statement is an example of this assertion.

Although JavaScript is the most widely used language, learning can be challenging. There are numerous additional symbols, including semicolons and curly brackets. 

Consequently, if you are learning a programming language for the first time and have no prior expertise with coding, Python performs significantly better than JavaScript in this regard. It uses simple variables and functions, which makes it easier for beginners to understand the language and start developing with it sooner.

  1. Versatility

While Python and JavaScript are both good web development, applications, and games, Python is used more in some strategic fields. Python is best at data analytics, AI(Artificial Intelligence)implementation, ML(Machine Learning), and in areas like Finance/Fintech.

Server applications, Web applications, games, and mobile applications benefit most from JavaScript. JavaScript additionally offers the benefit of being a front-end and back-end language. It has a significant advantage over Python in that it is not only a front-end language but also works incredibly well with the creation of the server-side logic of the application.

The server side is where Python ranks as a top back-end language.

  1. Performance

How fast a bunch of code runs determines how quickly the web application loads. JavaScript is preferable to Python since it can handle several requests simultaneously, while Python can only process requests in a single flow. This is the justification for why many applications, like Facebook, Google, Amazon, and others, employ JavaScript.

For some reason, JavaScript continues to perform better. It uses one of the fastest engines available, the V8 from Chrome. Node.js is the language of choice for creating real-time applications due to its built-in speed.

JavaScript is the undisputed winner when comparing Python and JavaScript in terms of performance. Python-based software will take longer to respond to, which keeps users waiting.

  1. Inheritance

JavaScript and Python support inheritance but use different mediums. Python utilizes a class-based inheritance paradigm, whereas JavaScript uses a prototype-based inheritance model.

Another difference between Python and JavaScript is that Python lacks a mechanism for inheriting from instances, but JS does.

  1. Mutability

Python and JavaScript are both mutable and immutable languages. In JavaScript, only objects and arrays are changeable, whereas, in Python, mutability refers to the ability to change an object.

The values of mutable objects are changeable after you assign value to them. But immutable objects can’t change their values. Objects, arrays, and sets are examples of mutable elements in Javascript, whereas numbers, texts, and boolean values are examples of Python.

  1. Procedural Programming

Both Python and JavaScript use a multi-paradigm approach, which means they enable multiple paradigms of programming. Both provide functional, imperative, and object-oriented programming paradigms.

  1. Application Development 

Building a website or native application is made easy with JavaScript. It allows you to build mobile and web applications. 

On the other hand, you cannot build mobile applications with Python since it does not have built-in mobile development capabilities. But you can develop mobile apps with packages like Kivy, PyQt, or even Beeware’s Toga library.

Python is appropriate for the back-end and other activities, including data analysis, machine learning, and operations that need a lot of math.

  1. Scalability

If you compare Python vs. JavaScript, scalability and multithreading are significant factors. This is because multithreading is an advantageous way to facilitate scaling.

Since Python only supports single-threaded systems and does not support multithreading, Node.js exclusively supports asynchronous programming. JavaScript is hence beneficial for web application scalability.

On the other hand, Python excels with rich built-in data structures, dynamic binding, and dynamic typing. You can use Python as a scripting language that integrates the existing components and helps us build scalable applications.

  1. Popularity 

Approximately 69.7% of the development community is said to use JavaScript, making it more popular than other web development languages. Comparatively, 41.7% of developers said they were most comfortable using Python.

Additionally, JavaScript is your best bet for creating mobile apps. It ensures web developers gain access to other employment opportunities. As a result, developers frequently choose it.
