Differences Between Python vs JavaScript

What is Python?

Python is an interpreted high-level programming language with dynamic semantics and object-oriented programming designed to be easy to read and implement. It is a scripting language like Perl/ruby and used for creating web applications too. It allows programmers to use different program styles for simple and complex programs. It came up with huge built-in modules and packages. Python supports different programming paradigm as object-oriented programming, functional programming, imperative programming and procedural programming.

What is Java-Script?

Java-Script is an object-oriented programming language which allows you to create dynamic web pages and got standardized in ECMAScript language specification. Java-Script supports different programming paradigm as object-oriented, functional, and imperative programming but not procedural programming. It is highly used in browsers to provide dynamic functionality which we cannot achieve through normal HTML and CSS. It has support for standard applications with text, regular expressions, and date.

Below is the Top 11 Comparisons Between Python vs JavaScript

Key Differences Between Python vs JavaScript

Some of the points are explained below that shows the Differences Between Python vs JavaScript

• Python is strongly typed – no implicit conversion between types whereas JavaScript is weakly typed.
• The synchronous and blocking code is standard in JavaScript whereas python as de-facto as default.
• JavaScript can be used to run on frontend whereas python is on server side programming or backend.
• Python has procedural programming whereas Java-Script does not have.
• Java-Script has; as statement terminator whereas python has a newline.
• Python is a better-designed language which makes it easy to maintain whereas JavaScript is poor.
• Python is not good for mobile development whereas Java-Script is good.
• Python is slow to run comparatively to JavaScript.
• Python provides huge standard library whereas JavaScript has a limited standard library.
• Python heavily relies on assignment with no difference between variable and assignment whereas JavaScript doesn’t relay.
• Python has many libraries for scientific computing, data analytics, and machine learning whereas JavaScript does not.
• Python has support for many numeral data types like int, float, fixed-point decimal whereas Java-Script mainly works on floating point variables.
• Python has inbuilt REPL whereas JavaScript does not have.
• JavaScript runs on both browser and server whereas python is mostly used for server-side programming.
• Python is easy to get started comparatively to JavaScript.
• Python is easy to find new jobs comparatively to JavaScript in this year.
• Python object-based is nearly equal to JavaScript and python supports programming style which uses simple functions and variables.
• JavaScript is most complex modern programming language comparatively to python.
• Python and JavaScript both use a lexical scope with small differences.
• Python has a Self-argument as the first argument for each method whereas JavaScript has accessed the object using “this”.
• Unlike JavaScript, python does not have a way to inherit from instances.
• Python is good if we do data analytics, machine learning or math-intensive operations whereas JavaScript is good for building a website or native applications as it took less time for UI work.

Comparison Table Python vs JavaScript

Following is the comparison table Differences Between Python vs JavaScript

Basis for comparison	python	JavaScript
REPL(Read-Eval-Print-Loop)	We will get it with the installation of python and call different python versions depending on our installation.	Whereas for Java-Script we didn’t have inbuilt REPL as most of the time we run in a browser. But we can use REPL by installing node.js
Mutability	Python has mutable and immutable data types like set (mutable) and list (Immutable).	Whereas Java-Script has no concept of mutable and immutable
Strings	In python source code is ASCII by default unless we specify any encoding format	Whereas Java-Script should be encoded as UTF-16 and no built-in support for manipulating raw bytes
Numbers	In python, we have different numeric types like int, float, fixed-point decimal etc.	Whereas Java-Script has only floating point numbers only.
Hash tables	Python has built-in hash tables, called dictionaries, sets etc which can be used in the hash with keys and values.	Whereas Java-Script has no built-in hash table support
Inheritance	Python uses class-based inheritance model. Let us consider an example as below: class  Welcome: def  __init__(self,name): Popular Course in this category Python Certification Course 19 Online Courses | 100+ Hours | Verifiable Certificate of Completion | Lifetime Access 4.8 (602 ratings) Course Price ₹19999 ₹113999 View Course Related Courses Programming Languages CourseAngular JS Certification Training self.name=name def   greet(self): print (‘hello, I am’ + self.name) From the above example shows you a class definition and __init__ function is a constructor.	Whereas Java-Script uses prototype based inheritance model. Let us consider an example as below: we need to create a function where we used classes in python as below: Welcome  = function(name){ this.name=name Python Certification Course 19 Online Courses | 100+ Hours | Verifiable Certificate of Completion | Lifetime Access Watch The Course Preview this.greet =function(){ return “Hello, I am “ + this. name }}
Code Blocks	Python uses indentation	whereas java-script uses curly brackets
Function arguments	Whereas python will raise an exception if a function is called with incorrect parameters and accepts some additional parameter passing syntax.	Java-Script doesn’t care whether functions called with exact parameters are not as by default any missing parameter gets a value as “undefined” and any extra arguments end as special arguments
Data types	Whereas python has two similar data types list and tuple. Python’s list and Java-Script array are quite similar.	Java-Script has inbuilt array type.
Properties and Attributes	Python allows defining an attribute using descriptor protocol where we can use a getter, setter functions	Whereas Java-Script objects have properties which can be composed of underlying attributes and it lets you define a property
Modules	Python calls itself as a battery included language as it comes with a wide range of modules	Whereas Java-Script comes with very few modules like date, math, regexp, JSON and it has the functionality available through host environment like a web browser or some other environment.

Conclusion Python vs JavaScript

Finally, it is the overview of Python and JavaScript and I hope that you have learned at least a few points after reading this Python and JavaScript article.

The difference between Python and JavaScript languages is very minimal as you can do almost everything with both Python and JavaScript languages as they share common things like lexically scoped, object-oriented, interpreted, functional and imperative programming. If some feature is missing in any language we have plenty of existing libraries and other extensions with which we can achieve whatever needed.

I felt that hopefully, you will have a better understanding of these programming languages. If you want to suggest me which one is better to learn first, I would suggest python as it has a good market in the IT industry and easy to learn also.
