Python Vs JavaScript - What are the differences?

Python and JavaScript, both are powerful scripting and coding languages with various real-world apps. Both languages compete with each other at the broad level in the current world. In this blog, Python Vs JavaScript, we will look into the key differences that both languages have. The difference between Python vs Javascript explains to us the major uses of both coding languages in different fields. 

Before we go deeper into the Python Vs JavaScript comparison, we should know them individually first. Let us look at what are Python and JS actually in a brief context.

Python is nothing but a beautiful coding language with high-level interpretation and dynamic semantics. It is designed with the OOPs model and is very easy to read and apply to every programmer. Moreover, this coding language supports different coding models, OOPs, functional, and imperative programming. It also helps programmers to script easily complex codes using various in-built modules and library packages.

JavaScript is a popular scripting language with an object-oriented programming model that supports the development of interactive web pages. This language provides dynamic functionality to the web pages. And this is not possible to get through typical CSS and HTML scripts. Moreover, JavaScript is useful across different areas like front-end, back-end, mobile, desktop, etc.

Thus, this is in brief about both programming languages in the Python vs Javascript comparison. Let us look at the major key differences between them in further context.

Python vs Javascript which is better

Here in this section, we will check the key differences for Python Vs Javascript and also try to find out the better one. There are many important things to differ them in a broad way depending upon various factors. The following are the Python vs Javascript comparisons.

Python is the high-level oops concept-based coding language that includes many built-in data structures with dynamic typing and binding. JS on the other hand is also a popular scripting language that follows client-side coding rules. 

Python vs Javascript

Javascript is useful for different technologies like REST APIS, XML, Node.JS, etc. Python language also has different uses that include data analysis and web app development.

In the python vs javascript comparison, python includes the concept of mutable and immutable data types. But JS doesn’t have such a concept. 

Javascript uses curly brackets while writing the scripts/codes whereas Python language uses indentation. 

Python is useful in dealing with tasks like data analysis, ML, and other mathematical operations. On the other hand, JS is useful for building native apps or websites dynamically.

The language Python includes various numeric values like int, fixed point decimal, etc. On the other side, Javascript only includes floating-point numbers. 

Javascript needs encoding into UTF-16 as it doesn’t consist of any in-built support for modifying raw bytes. Python, on the other hand, includes ASCII code by default even a use don’t specify the encoding format.

Python language uses an inheritance model class-based whereas Javascript uses a prototype-based model of inheritance.

JS includes a few modules like math, date, JSON, etc., but Python language includes different types of modules.

To define an attribute, the python coding language uses getter and setter functions. On the other side, JS uses a composition of underlying attributes to define a property.

JS is useful in front-end, & back-end development along with mobile app development additionally. Where Python is not suitable for mobile app development.

Python vs JavaScript performance

The coding language Python is a little bit slower in performance as it processes various requests in a single flow. There are many ways to optimize Python’s performance where it includes updated libraries like Numpy and Cython.

JS on the other side works much faster on the web than Python. it works well with I/O situations  (Input/output) where a huge amount of data moves to and through the app in real-time. The best suitable example for this is “Facebook”.
