Python vs. JavaScript: What Is the Difference?

Python and JavaScript have become two of today’s most popular programming languages. Each is an object-oriented programming language, but their contexts are distinctive. Moreover, Python and JavaScript are fantastic options for beginning a coding career since they are very straightforward to learn and have plenty of work prospects. Even if Python and Javascript are used to create web applications, their scope of use differs. So, Python vs. JavaScript: What is the difference? 

What Is Python?

Python is a high-level programming language that promotes code readability while allowing developers to work quickly and effectively. Python is used to develop online apps, games, artificial intelligence, and machine learning.

It is intended to be simple to understand and apply. As a result, it is frequently rated as one of the simplest programming languages. Python may also be used to create web apps in the same way that Perl and Ruby can. Python’s appeal is that it enables programmers to apply various programming methods to assemble complicated and straightforward programs.


What Is JavaScript?

JavaScript, sometimes called JS, is an object-oriented programming language commonly used to create dynamic web pages. The application’s front end is the part with which the user interacts. Whenever you see or contact a website or online application, JavaScript is employed “behind the scenes.”

It should be noted that using Javascript does not necessitate the usage of a compiler or any other software. All major browsers, including Google Chrome, Firefox, and Safari, can process Javascript code.

Javascript code is placed on an HTML page and is processed immediately by a web browser. It is just a simple scripting language utilized by technology giants like Google, Wikipedia, and others.

Python vs. JavaScript Head-to-Head Comparison

The fundamental distinction between Python and JavaScript is as follows:

Tuples, Arrays, and Lists

As built-in data types, arrays are supported by JavaScript. Although Python does not have built-in support for arrays, there is still a method for generating arrays in Python. This is accomplished through lists, Python’s equivalent of collections.

Python lists are comparable to tuples, another data type supported by the computer language. The primary distinction between a list and a tuple is that the former is variable, while the latter is immutable.

Blocks of Code

Curly brackets are used in JavaScript to define code blocks. Python, on the other hand, defines code blocks using indentation. While JavaScript employs a semicolon (;) as a statement ending (though not required), Python uses a newline.

Properties and Attributes

JavaScript objects contain properties, which are made up of underlying attributes. It allows you to specify a property. For example, the descriptor protocol, which uses getter and setter methods throughout the Python programming language, will enable you to set an attribute.

Format of Encoding

JavaScript should be UTF-16 encoded. Furthermore, the programming language lacks the built-in capability for manipulating raw data. Therefore, unless otherwise stated, Python source code uses ASCII by default.

Tables with Hash Functions

Hash tables have indexed structures that let you specify a set of matched values. As a result, they can be used for finding, inserting, and deleting data more quickly than traditional methods.

Python programming language has built-in hash tables such as dictionaries, sets, etc. The Dictionary data structure is used to describe hash table implementation. Hash table functionality is available in JavaScript, mainly in the map type and set.


Python and JavaScript both enable inheritance. The distinction is in their classifications. Python utilizes a class-based inheritance paradigm, whereas JavaScript utilizes a prototype-based inheritance system. Another difference between Python and JavaScript regarding inheritance is that Python cannot inherit from instances, but JS does.

Mobile Application Development

JavaScript is a fantastic choice for mobile development concerning front-end and back-end programming. On the other hand, Python is not commonly utilized for creating mobile applications. In recent years, though, several developers have used Python for mobile programming.

Number Forms

Floating-point variables were the only ones available in JavaScript. Modern web browsers, as well as the V8 engine, however, offer a new fundamental type: BigInt.

In contrast, the Python programming language supports various numeric data types, including int, fixed-point decimals, and float.

Procedural Programming

Python and JavaScript both use a multi-paradigm approach, allowing several programming paradigms.

Python and JavaScript both provide functional, imperative, and object-oriented programming techniques. On the other hand, Python contains numerous procedural programming features that JavaScript does not.

Python vs. JavaScript programming


Mutable objects have values that can be modified after they have been set values. Immutable objects, on the other hand, cannot change their values. In Python, data types are classified as changeable or immutable. The set, for example, is a changeable data type, whereas the list is a firm type of data.

There are also mutable and immutable types of data in JavaScript. Objects, arrays, and sets are instances of the former, whereas integers, texts, and boolean values are examples of the latter.


JavaScript is perfect for creating a website or native app. On the other hand, Python is well-suited to a wide range of tasks, such as data analytics, math-intensive procedures, and machine learning.

Python Application

Python is a robust programming language with an easy-to-use interpreter. A Python program is also reasonably simple to comprehend. Python is an object-oriented programming language that, as previously stated, supports a range of development methodologies, including structured and functional programming.

As an outcome, it can be used to build complete software. Contract and logical programming are also available, but only with the help of extensions.

Python may serve as a functional scripting language. Whenever it refers to client-side coding, Python is frequently used. As a result, users may claim that Python allows for the development of simple and complex programs using various programming methodologies.

JavaScript Application

Javascript is a programming language that has risen in importance to the point that one might only be able to operate as a developer. Its primary use is client-side scripting.

The debut of Javascript signaled the beginning of a period of interactive websites. If you have learned HTML, you know that HTML is used to display static material on a website page, and CSS is used to design web pages. Javascript, on the other side, allows us to create dynamic web pages.

As a result, it’s frequently used to make dynamic web pages. It allows us to receive and validate user input. Javascript may generate dynamic online content by employing drop-down menus, animations, mouseover action, and other web page components. It was initially intended for front-end development but is also currently used for back-end development.

Advantages of Python

  • It is an Object-oriented high-level language with user-friendly data structures.
  • Python is a universal programming language on various platforms and operating systems.
  • It supports multiple libraries ( Pandas for data analytics, NumPy for numerical calculations, etc.).
  • Extremely Effective (Python’s transparent object-oriented design increases control systems, and the language has excellent text processing and integration capabilities)
  • Python may help you simplify complex programming. Garbage collection is necessary since it works with memory addresses internally.
  • Python also has an interactive shell that allows you to test things before they are implemented.
