Python vs JavaScript: What is the Differences?

One of the developers’ biggest questions today is which programming language they should use. There are many different languages to choose from, each with its strengths and weaknesses, so it can be challenging to pick just one and stick with it. But Python and Javascript are two that seem to constantly be at the top of everyone’s list of essential languages to learn. Are they all that different? Or does it come down to personal preference? Let’s find out the most significant differences between Python and Javascript.

Main Difference

Python and JavaScript are two of the most popular programming languages in the world. They both have pros and cons, but which is best for you? Python is a powerful programming language that is widely used in many industries. It is known for its readability, flexibility, and comprehensibility. Python is perfect for beginners because it is easy to learn and has a wide variety of libraries that can be used for any purpose.


JavaScript is also a popular language that is used for web development. It is known for its flexibility and ease of use. JavaScript can be used on the front-end or back-end of a website, making it a versatile tool for web developers.

Introduction To Python

Python is a high-level, interpreted, general-purpose programming language. It was designed to make writing clear, concise programs easier than in languages like C++, Java, Perl, etc. Python’s syntax is similar to English, making it easy to learn. Python is a dynamic language, meaning that variables are assigned values at runtime (as opposed to compiling time). This makes it possible to write flexible software. Python supports object orientation, modularity, exception handling, recursion, and iteration.


Many companies are using Python. Here are some examples:

  • Google uses Python extensively for its internal systems.
  • Facebook uses Python to power its social networking site.
  • NASA uses Python to run simulations for space missions.
  • Netflix uses Python to stream movies and TV shows.

Introduction To Javascript

JavaScript is a scripting language developed by Netscape Communications Corporation (now known as Mozilla) and released in 1995. Initially designed for web browsers, it became famous as a general-purpose programming language.

The primary function of JavaScript is to provide dynamic interactivity between web pages and web applications. Dynamic interactivity means that users can manipulate data without reloading a page. JavaScript enables web developers to create interactive websites and web applications using standard web browser technology.

Similarities Between Python and JavaScript

1. Both languages have similar syntax

Both languages use curly brackets (“{}”) to define blocks of code. In addition, both languages use indentation to indicate nesting levels.

2. Both languages have keywords

In both languages, keywords are reserved words that cannot be used as identifiers. Keywords include if, else, while, do, etc.

3. Both languages have variables

Variables are declared using the var keyword. Variables are assigned values using the operator.

4. Both languages have arrays

Arrays are defined using square brackets. Arrays are indexed using integers.

5. Both languages have objects

Objects are created using the new operator. Objects inherit from their parent classes.

6. Both languages have strings

Strings are enclosed in double quotes (“). Strings may be concatenated together using +.

7. Both languages have operators

Operators are used to performing mathematical operations.

Differences Between Python and JavaScript

1. Syntax: Python vs. JavaScript

Javascript syntax is similar to python syntax. Both languages use indentation to indicate code blocks. However, javascript uses curly brackets instead of an indentation.

2. Variables: Python vs. JavaScript

Variables in python are declared using the var keyword. In javascript, variables are declared using the let keyword.

3. Functions: Python vs. JavaScript

Python has functions while javascript does not. A function is a block of code enclosed in parenthesis.

4. Loops: Python vs. JavaScript

Loops in python are indicated by the for a loop. In javascript, loops are indicated by the for-in loop.

5. Classes: Python vs. JavaScript

Classes are created in python using the class keyword. In javascript, classes are created using the function keyword.

6. Inheritance: Python vs. JavaScript

Inheritance is done differently in python than in javascript. In python, inheritance is done using the super() method. In javascript, inheritance is done using prototypal inheritance.

7. Objects: Python vs. JavaScript

Objects are created in python using object(). In javascript, objects are created using the {} operator.

14 Key Differences Between Python and Javascript

  1. Python is a high-level programming language designed to make writing code easier.
  2. Javascript is a low-level scripting language that is commonly used to create interactive web pages.
  3. Both languages are object-oriented and have similar syntax.
  4. Python is generally faster than Javascript.
  5. Python is generally safer than Javascript.
  6.  Python is generally more secure than Javascript.
  7. Python is generally more potent than Javascript.
  8. Python is generally simpler than Javascript.
  9. Python is generally easier to learn than Javascript.
  10. Python is generally easier than Javascript to use.
  11. Python is generally easier and less expensive to maintain than Javascript.
  12. Python is generally more portable than Javascript.
  13. Python is generally more popular than Javascript.
  14. Python is generally more widely supported than Javascript.

Comparison Chart Between Python and JavaScript



It is a high-level programming language that is object-oriented. JS, or Javascript, is a scripting language.
Guido van Rossum is the creator of Python. Brendan Eich (Netscape) created Javascript, which ECMA presently maintains.
Python makes it simple to read and maintain code. Because of its flexibility, Javascript does not provide easy code readability or maintainability.
To run Python code, you’ll almost always need an interpreter. The ability to run Javascript code is built-in to most web browsers.
It’s a dynamically typed language as well. It’s a dynamically typed language as well.
For server-side scripting, Python is commonly used. Client-side scripting is the most common use of Javascript.
By default, it is encoded as ASCII. It has the UTF-16 encoding.

How they stack up against each other

Both Python and JavaScript are high-level, interpreted programming languages. They’re also object-oriented, meaning they can store data in variables and manipulate it with functions. However, there are some critical differences between the two languages. One of these is their design philosophy: Python was a precise language for teaching programming and a functional language for real-world use. Conversely, JavaScript was designed to make it easier to interact with web pages. Another significant difference is how each handles data types (e.g., strings).


In conclusion, Python and JavaScript are both versatile, popular programming languages that can be used for various purposes. While they share some similarities, they also have several key differences. Python is a more robust language with a greater focus on code readability, while JavaScript is more lightweight and allows for more flexibility. Ultimately, the decision of which language to use depends on the specific needs of the project.
