Python vs JavaScript: Difference You Should Know

Python vs Javascript

Python and JavaScript are two popular programming languages out there. Both are high-level programming languages and free to use.

Python is an Object-oriented language used on a large basis for web and app development. Python is very useful in the field of Data Science and Rapid Application Development. While JavaScript is a programming language, if we discuss it more specifically JavaScript is a scripting language because it embedded in HTML which is a markup language.


Difference between Python vs JavaScript

Both languages possess a bright future in upcoming years. On the web, JavaScript dominates over Python.

Before we compare two languages (Javascript vs Python)  let’s have a brief introduction of both.



This is one of the most trending languages out there. It was first introduced in 1991 by Guido van Rossum who is the creator of Python. From the beginning, it is a high-level language that follows the concept of OOP’s. 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 comparable to every other programming and scripting language. It is used for many purposes such as Data Analysis, Scientific Analysis, Machine Learning, Building applications, 2d and 3d games, Web application, and lots more. Even after multiple uses and applications of Python, it is not that much popular as compared to JavaScript. The big players such as NASA and Google are boosting the demand for javascript across the world.

Example of Python Programming

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

JavaScript is a high-level programming language that is used as a scripting language for both the client-side and server-side after Node JS. Like other languages, JavaScript does not need any compiler, interpreter, or assembler to run its files. It can simply run on the web browser.

Often people have the confusion that JavaScript is related to Java because of the initials of both the language; let me tell you that JavaScript is completely other than Java except the prefix Java only else they are not related.

JavaScript was designed by Brendan Eich back in 1994 when the web pages were work on only HTML and CSS. JavaScript is one of the most popular among all scripting languages. The main function of JavaScript is to create Dynamic Web pages that can make the interactivity more amazing between the user and the server. Big giants such as Facebook, Twitter, and many more are using JavaScript on their web pages for the dynamic Interface.

JavaScript is just not limited to web Pages it is also used to build 3d Games, manage databases, and a lot more.

Example of JavaScript Language

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

What to choose between Python or JavaScript?

What language you should choose is basically depends on what you want to do with the Programming Languages in your future. Often People ask which programming language they should choose that can make a good career so, to be honest with any language Python or JavaScript you can make a successful and growing career, the condition is 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 these questions like why you want to learn this language, are you up to build some amazing dynamic web pages, or you want to work on Artificial Intelligence, or you want to be a data analytical, or you just want to learn code. After understanding the constraints go for the right Programming Language.

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

Python vs JavaScript: 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 file. The JavaScript files can be simply run on Browser.
Python files can run on Windows, Linux, and Mac, but to do so you need to download the Python Interpreter. It is platform-independent; it can run on all platforms, it 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 the difference is it uses C notation and curly brackets for closures and blocks.
Python has a different number of data types such as integers, floats, etc. 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.
Python use indentation to indicate what block of code a statement belongs to. JavaScript Use curly braces.
Python has many datatypes which use index call those are list, tuple, sets, and Dictionaries. JavaScript only has Array which uses index call, however, the syntax of calling an array and list is the same.
Python follows the concept of OOPs. JavaScript also follows the concept of OOP’s.
Python has the concept of Mutable and Immutable data types. JavaScript does not have the concept of mutable and Immutable datatype.
Python has tons of libraries including third-party. JavaScript supports a large community.

Advantages & Disadvantages of JavaScript and Python

Advantages of JavaScript

  • It can run on any browser.
  • The speed of JavaScript is very fast, as it can run on client-server directly, which 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 is using JavaScript.

Disadvantages of JavaScript

  • The JavaScript code is not secure the code is always visible.
  • The JavaScript DOM (Document Object modulation) 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 write on the file.

Python Advantages

  • It is quick and easy to learn from other object-oriented languages.
  • It supports multiple platforms to run and platform like on Mac, it comes pre-installed.
  • 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 concept.
  • It has a large number of Libraries.

Python Disadvantage

  • Python doesn’t do multi-core and multi-processor well.
  • There is a limitation to access the Database.
  • It is slow as compared to other languages such as JAVA and JavaScript.
