 Python vs Javascript - making an informed decision.

Choosing the right language is the most important step in the whole process of developing an application. Today we are going to discuss, compare and help you choose two most popular programming languages - Python and JavaScript.

Both Python and Javascript has some powerful tools to make technologies that make a difference. Each language has its own strengths and weaknesses, different use cases and distinct features.

Javascript has emerged as a strong language in the world of web development whereas Python has spread its roots to various domains including software development, web development, machine learning and others.

Python vs Javascript (or any 2 computing languages) is not really a contest where one would win and others would lose forever. Python vs Javascript is subjective to the application you are making, the use case, your familiarity with the language and a lot of other factors.

In order to make an informed decision on Python Vs JavaScript, we need to have a strong knowledge of both these languages. We'll begin our blog on Python Vs JavaScript by understanding the language of Python first.

What is Python?

Python, invented by Guido van Russum in 1991 has been at the top of the stack for many years now. According to the formal definition, Python is an interpreted, high-level and general-purpose programming language.

Python is a programming language that falls in the category of object-oriented programming language. If you are confused about the object-oriented nature of Python, here are some points for you to comprehend the principles of an object-oriented language.

Python is an object-oriented programming (also called OOP) language because it follows all the principle of an object-oriented language. Applications written in Python language are based on declaration of classes, creation of objects and the interaction between these objects. We would now understand each of the basic principles of Python or any other object-oriented programming language in brief. The basic principles of object-oriented language are -


Inheritance is the name given to the concept when the child class derives properties and methods from the parent class. There are various types of inheritance in Java.


The next feature in line is encapsulation. This feature refers to the property of wrapping up of data together as a single unit. Encapsulation lets you hide the variables of one class from other classes. The variables of one class can be accessed from the method of that class only. Encapsulation is also called data hiding.


Abstraction is another feature of OOPs. Abstraction lets you hide certain details and show only the relevant and necessary information. Abstraction is an important factor for the security of any application.


Polymorphism is the last feature we would discuss. The word polymorphism basically means many forms. In a programming language, polymorphism is the ability of an object to take on many forms. In a programming language, if a method acts differently based upon the object, it is called polymorphism. It is an important concept of object-oriented programming language.

While these were only some basic principles of an object-oriented language, there is more to it. Object-oriented programmes create an object which has properties and methods. These objects interact with each other to perform specific actions. Objects, classes, methods, properties and others are important aspects of object-oriented programming languages.

The object-oriented model decreases the complexity of the code and gives programmers the flexibility to create dynamic applications by mimicking real-world objects.

Python in Industry

Python has emerged as the most favourite language of developers. The credit goes to easy syntax and a number of libraries to support your code.

Python can be used as a language to build a full-scale software program right from scratch and it can also be used as a scripting language. Python is not a dedicated scripting language, rather it can be ‘used’ as a scripting language and the credit goes to its easy to learn object-oriented syntax.

Python has a rich collection of libraries and frameworks that aid a programmer to build real-life applications with the utmost ease.

One of the major reasons why this is one of the best programming languages of 2020 is its wide range of applications. From desktop applications to web frameworks and applications, python has a number of use cases. Python is also the most important language in machine learning and artificial intelligence which are one of the most promising fields in the upcoming years.

Google uses Python as a part of its search engine and Yahoo also uses Python as a part of Yahoo maps. Organisations like Microsoft, Youtube and Cisco also have Python as one of their main technologies.

Python is definitely a rewarding language in 2020. Good knowledge of python is definitely going to help you land a successful career in technology.

Now that we have enough knowledge about Python, it is the right time to move ahead with Javascript.

What is Javascript?

Javascript, founded by Brendan Eich back in 1995 was initially used for browsers and creating interactive web pages. Javascript is an event-driven, functional and imperative language. It is popularly used to make dynamic effects on web pages like rollover, rollout and other interesting functionalities. It is also used to make both server-side and client-side applications.

Basically, Javascript is a scripting language that adds complex features on the web. Javascript is primarily a scripting language and over time it has diversified in its use case.

Whenever you see a scrolling video jukebox, animated graphics or simply an update, chances are that Javascript is at work. On a webpage, Javascript works in coordination with HTML and CSS.

Javascript was designed to run on browsers and hence every browser has a Javascript engine. Chrome’s v8 engine is an example of Javascript engine. In 2009, Ryan Dahl created the Node, a C++ program that included Chrome’s v8 engine. Nodejs allows you to run javascript code outside of a browser.

With the advent of Nodejs and other advancements, Javascript has now diversified and has moved to other environments and can now develop a wide range of applications.

Let us have a look at what all Javascript can achieve in today’s time.

  • Firstly, it is now used at the server-side also. Nodejs is a framework which is used for server-side web development.
  • Javascript can also be used to make stand-alone desktop applications. Electron js is a cross-platform framework used to build standalone software applications.
  • React is used with Javascript to create dynamic web and mobile applications. React native is used to create dedicated mobile applications only.
  • Angular is another framework, developed by Google, that can be used with Javascript in order to make dynamic web applications. It is a Model View Controller Framework.
  • React vr is another interesting thing that has emerged which is used to make virtual reality applications.
  • Tensor flow has become very popular lately. It is a javascript library that can be used to train machine learning models.
Javascript in Industry

Now that we have seen the various uses of Javascript in different domains, you can easily understand the importance of Javascript in the world of technology.

It is used by giants like Netflix, Uber, Paypal to create dynamic webpages that are fast and secure. Javascript has become one of the most popular languages used in the world of technology

Now that we have understood the basic concepts of both the languages Python and Javascript, we shall now look at Python vs Javascript.

Python vs Javascript

We have garnered enough knowledge about both Python and Java, it is time we look at some of the parameters that differentiate these two powerful languages. It is time we begin Python vs Javascript.

Python and Javascript have emerged to be powerful languages of this century. Both these languages are powerful, fast-growing and efficient. We saw earlier in the same blog that Python and Javascript are used by some of the top companies in the market.

Here we are going to look at some parameters that differentiate both these languages and help you make the right choice next time you build an application.


The first parameter in our list is Nature. Python, as mentioned above, is a high level, object-oriented programming language whereas Javascript is an object-oriented scripting language. Python supports class-based inheritance and hence developers can take advantage of code reusability to make the process of developing applications easier. Javascript supports prototype-based inheritance models. To know more about prototypes in Javascript, you can refer to this article.


The popularity of any language plays an important role in determining its success. Both Javascript and Python are immensely popular, loved and wanted amongst the developer community. These languages often grab close spots in different surveys conducted by organisations.

However, popularity shall not be the only factor you should consider while choosing a language for your next development project.

Use cases

Python and Javascript are used for making different kinds of applications in different scenarios. Python, for example, is a cross-platform language which makes it easier to develop a plethora of applications. With Python, you can make a web application, develop games, implement machine learning projects, artificial language and data science. It can also be used for desktop GUI, CAD applications and a lot of other applications.

On the other hand, Javascript is popularly used for web applications, websites and client-side development. With the advent of Nodejs, Javascript had diversified to server-side applications IoT applications and a lot of other domains also.


Syntax, as you must be aware, is a set of rules that define the features and functionalities of any language. The syntax of both languages is a good parameter to differentiate.

A major reason behind Python’s popularity is its easy syntax. Python is designed to resemble the English language. There are brackets or semicolons to make the code easier. In Python, you don’t even need to mention the data type of the declared variable. Javascript uses the naming convention that is similar to Java however the syntax of Javascript is similar to the C language.

Exception Handling

In programming languages, exception handling makes sure that the flow of execution doesn’t break if an error occurs.

In python, an exception is raised if a function has been called using incorrect or wrong parameters or if there is any other exception in the programme. Javascript doesn’t pay special attention to errors. For example, if the function has been called with missing parameters, it simply assigns a default value to the missing parameter.

With this, we come to an end of our comparison between Python vs Javascript. We have understood the basics of each language and compared both of them on various factors.
