Python vs JavaScript: Which is Better for Web Development

By | March 26, 2022
Python vs JavaScript

Python and JavaScript are two popular programming languages out there. Both are high-level programming languages, open-source and free to use. Python is an object-oriented language used primarily for web and app development. It is very useful in the field of data science and Rapid Application Development (RAD). JavaScript, on the other hand, is a scripting language that, along with CSS and HTML, forms the basis of modern websites. In this article, we will compare the two, i.e., Python vs. JavaScript.

Difference Between Python and JavaScript (Python vs JavaScript)

Both programming languages offer a bright future to developers. On the web, JavaScript dominates Python, but when it comes to data science and AI, Python comes out on top. Before we compare the two popular programming languages (JavaScript vs. Python), let’s have a brief introduction to both.



First introduced in 1991 by Guido van Rossum, Python is one of the most trending languages out there. From the beginning, it is a high-level language that follows the concept of OOPs. As it is an interpreted language, Python reads the source code line by line and executes it as the same.

In the current scenario, Python is the only sorted and popular language after Java. The versatile nature of Python makes it powerful than every other programming and scripting language. It is used for many purposes such as data analysis, scientific analysis, machine learning, application development, and 2d and 3d game development. Even after multiple uses and applications of Python, it is not that much popular as compared to JavaScript.

An Example of Python Programming

#Hello world on Python
print(“hello world”)
hello world

Advantages of Python

  • It is quick and easy to learn compared to other object-oriented languages.
  • It supports multiple platforms.
  • The syntax of the language is well organized and easy to read.
  • It is a dynamic language, so you do not need to define the variable datatype.
  • It has a large community.
  • Supports the OOPs concepts.
  • It has a large number of libraries.

Disadvantages of Python

  • Python doesn’t have good multi-core and multi-processor capabilities.
  • There is a limitation to accessing the database.
  • It is slow as compared to other languages such as Java and JavaScript.

JavaScript is a high-level programming language that is used as a scripting language for both the client-side and server-side. It does not need any compiler, interpreter, or assembler to run its files. It runs inside the web browser but can run outside the browser via NodeJS.


Often, people have confused that JavaScript is related to Java because of the similarity in the names. However, JavaScript is completely different than Java. While JS is a web scripting language, Java is a full-fledged programming language.

JavaScript was designed by Brendan Eich back in 1994 when web pages worked only on HTML and CSS. JavaScript is popular among all scripting languages. The main function of JavaScript is to create dynamic web pages that can make the interaction between the user and the server amazing.


Big giants such as Facebook and Twitter are using JavaScript on their web pages for developing dynamic interfaces. JavaScript is not just limited to web pages, but it is also used to build 3D Games, manage databases, and a lot more.

An Example of JavaScript Programming

#Syntax for popup alert box on the browser
alert(“Hello world”);

Advantages of JavaScript

  • It can run on any browser.
  • The speed of JavaScript is very fast. As it can run on client-server directly, this makes it very fast.
  • It is very easy to learn.
  • JavaScript is everywhere on the web. So learning JavaScript is a good career choice.
  • It has a vast community around the world.
  • It has a rich interface due to the drag-and-drop components.
  • Nowadays, almost every web page uses JavaScript.

Disadvantages of JavaScript

  • The JavaScript code is not secure. Also, the code is always visible.
  • JavaScript DOM (Document Object Model) is not fast.
  • Finding errors is very hard in JavaScript.
  • Even a single error can stop the whole site interface.
  • It does not have the concept of reading from the file or writing to the file.

Python vs. JavaScript: Which One to Choose?

What programming language you should choose among the two depends on what you want to do with the programming languages. Often people ask which programming language they should choose that can make a good career. To be honest, with any programming language, Python or JavaScript, you can make a successful and thriving career. The condition is that you need to be focused on what you are doing.

Both languages are doing great in their specific field. Before choosing between Python and JavaScript, you must know the answers to questions like, “Why do you want to learn this language? “Are you up to build some amazing dynamic web pages, or do you want to work on artificial intelligence? “Do you want to be a data analyst or just want to learn code?”. After understanding the constraints, go for the relevant option.

If you are a complete beginner and have no idea which language you should choose and have no future planning for any specific kind of project work, you can choose either of the programming languages, i.e., Python or JavaScript. Both languages are easy to learn, and you will enjoy coding on both.

Python vs. JavaScript: A Head-to-Head Comparison

Python JavaScript
You need to install a Python interpreter to run the Python file. JavaScript needs no interpreter or compiler to run its files. The JavaScript files can simply run in the browser.
Python files can run on Windows, Linux, and macOS, but to do so, you need to download a Python interpreter. It is platform-independent, and thus, it can run on all platforms. JS just needs a browser to run.
The syntax of Python is easier to learn as it uses spacing. JavaScript is also easy to learn, but in contrast to Python, it uses C notation and curly brackets for closures and blocks.
Python has different data types, such as integers and floating-point numbers. JavaScript has only floating numeric datatype.
Python has the concept of an associative list known as dictionaries. JavaScript does not have the concept of an associative array or list.
It uses indentation to indicate what block of code a statement belongs to. JS uses curly braces.
Python has many data types that use index calls. Examples are lists, tuples, sets, and dictionaries. JavaScript only has arrays that use index calls. However, the syntax of calling an array and list is the same.
Python follows the concept of OOPs. JavaScript also follows the concept of OOPs.
It has the concept of mutable and immutable data types. JS does not have the concept of mutable and immutable data types.
Python has many libraries, including third-party. JavaScript has tons of libraries.


That sums up the JavaScript vs Python discussion. As you can deduce, each has its own strong and weak points. Nonetheless, both are among the most popular programming languages and the best options to build a career in programming. If you can’t decide on one among the two, go for both.
