Before you begin writing your first lines of code, you must first select the appropriate programming language for your project. There are many languages to select from.
You may have come across two languages that piqued your interest: Python and JavaScript. These two languages are similar in several respects, but their use cases, grammar, and programming techniques differ substantially.

A bit About Python

Python’s strength and adaptability have made it an indispensable tool in nearly every scientific application throughout the world. It is a general-purpose programming language that can be used for many.

Data science, artificial intelligence, machine learning, computer science education, computer vision and image processing, medicine, biology, and even astronomy all make full use of it.

Python is also useful in web development. This is where we may begin to compare its applications to JavaScript. Python is used for back-end development(the frustrating part of web development) that is responsible for producing aspects that visitors do not see, such as the webserver side of an application.

A bit About javaScript

While Python may be used to create the back-end of a web application, JavaScript can be used to create both the back-end and the front-end(The front-end is the part of the programme with which the user interacts.)

Similarly, while interacting with a mobile app, you may be utilizing JavaScript since frameworks such as React Native allow everyone to create apps that adapt to multiple devices.

JavaScript is frequently used in web development because it is a powerful language that provides us with the tools we need to create online application components.

Let’s look at the advantages and disadvantages of both javaScript and Python!

Python vs JavaScript: which one is more popular in 2021?

JavaScript is still the most widely used programming language. However, Python’s trend has increased substantially in recent years, surpassing languages like java, C#, PHP, and C++ according to StackOverflow Developer Survey 2021.

Python vs JavaScript: which one offers more salary in 2021?

Python is currently the fastest-growing programming language, earning over $65k per year (median salary). JavaScript programmers are far behind, earning around $56k per year (median salary) according to StackOverflow Developer Survey 2021. The choice between Python and JavaScript is influenced by your future goals also.

Python vs JavaScript: which one is easier to learn in 2021?

In a nutshell, JavaScript is more difficult to learn than Python.

Python is typically the first programming language chosen by newcomers, particularly those with no prior programming expertise.

Python code is well-known for being more readable, which means it is easier to understand.

Python code contains fewer lines than code written in other languages such as C or C++.

In Python, there are very few structural principles. For example, you are not obliged to include a semicolon after each sentence.

It has a plethora of frameworks that include pre-written code to help you accelerate the development of your applications.

Python vs JavaScript: which one is better for web development in 2021?

There are numerous elements to consider when deciding whether to study Python or JavaScript for web development. You require a super – fast website that can manage the increasing quantity of data and code.


When comparing the performance of JavaScript and Python, JavaScript comes out on top. Python-based software will take longer to reply, rendering it inactive for the user community. As a result, if you want to create websites that are fast, you should utilize JavaScript.

When comparing Python and JavaScript, scalability is also an essential consideration.

It refers to a language’s ability to handle big numbers of users and manage vast volumes of data while utilizing minimum server utilization.

Node.js is scalable and enables asynchronous programming. As a result, Node.js is far better suited to the creation of programmes that rely on the speed of execution. 

JavaScript is essential if you want to become a web developer, particularly a front-end web developer.

On the other hand, the Python language has a fairly stable environment with frameworks such as Flask, Django, Pyramid, and CherryPy, ensuring that development becomes more rapid.

Python has front-end capabilities, however, we do not suggest replacing front-end languages with Python. Browsers do not yet support Python execution. As a result, you have to convert Python to JavaScript before you could use it.

Even though you can convert Python to JavaScript, the code interpretation slows down the execution process. 

As a result, JavaScript triumphs in the web component of Python vs. JavaScript.

Python vs JavaScript: which one is better for Machine Learning in 2021?

Python has long been the preferred language for machine learning applications. It has a wide catalogue of packages with built-in functions that aid in data analysis and processing, cleaning, modelling, and visualization, among other things. TensorFlow, Keras, and Theano are examples of frameworks that make it simple to implement different machine learning capabilities. Many developers believe Python to be the best language for ML projects due to its flexibility to connect with various languages and platforms, as well as its extensive data handling capacity.

While most JavaScript machine learning libraries are relatively new, particularly when compared with Python, they are fully able to support several major ML use cases. Furthermore, new ones are constantly being created, with a particular emphasis on computational data, data analysis, and performance optimization. Because of the computational expenses, frontend JS machine learning libraries are often used for existing, pre-trained models, whereas training new ML models is done on backends such as Node.js.

Python appears to be the language of choice for the vast majority of machine learning applications. However, this does not have to be the case in all instances. Going with JavaScript may be more feasible in machine learning web applications.

Python vs JavaScript: which one is better for Mobile Development in 2021?

Python has traditionally not been used to create graphical user interfaces (GUIs). However, frameworks like Kivy and BeeWare enable Python mobile programming.

Kivy is an open-source Python library with its own UI toolkit that includes versions of buttons, text entry forms, text labels, and so on. It is compatible with both Android and iOS.

JavaScript mobile development has both advantages and downsides. The first item to mention is that JavaScript’s primary role is to construct and administer websites; mobile development is a secondary one. Nonetheless, JavaScript mobile development is more sophisticated than Python.
Another drawback is that native JavaScript apps are not supported by iOS and Android phones. As a result, hybrid apps such as PhoneGap, Sencha, or Kendo UI are needed.

You may use these frameworks to develop mobile apps that use JavaScript, HTML, and CSS. The finished product may then be bundled into mobile applications. Other popular libraries for creating mobile applications using JavaScript include React.js and Angular.js.

Python vs JavaScript: Conclusion

You may still wonder if you should study Python or JavaScript. We propose that you concentrate on the major field in which you wish to learn. For example, if web development is your passion, you should examine the holy trinity of HTML, CSS, and JavaScript.

When it comes to Python vs. JavaScript, anyone interested in machine learning, data science, and neural networks should start learning Python.

Furthermore, the conclusion of the Python vs. JavaScript debate is related to your experiences and tastes. Python, for example, may appeal to novices because of its simple syntax.

While Python may be used as a frontend language, transpilers that translate Python code to JavaScript slow down apps.

As a result, it is preferable to utilise Python for backend development and JavaScript for frontend development.

If you have selected one of these two languages, you should begin learning it right now!
