Difference Between Python vs JavaScript

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 is also used for creating web applications. Java-Script is an object-oriented programming language that allows you to create dynamic web pages and got standardized in ECMAScript language specification. Java-Script supports different programming paradigms as object-oriented, functional, and imperative, but not procedural.

What is Python?

Python supports different programming paradigms, such as object-oriented, functional, imperative, and procedural. It came up with huge built-in modules and packages. It allows programmers to use different program styles for simple and complex programs.

What is JavaScript?

Java-Script is an object-oriented programming language. It is highly used in browsers to provide dynamic functionality, which we cannot achieve through normal HTML and CSS. It supports standard applications with text, regular expressions, and dates.

Key Differences Between Python vs JavaScript

Some of the points are explained below that show 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 is de-facto as default.
  • JavaScript can run on the front end, whereas Python is on server-side programming or backend.
  • Python has procedural programming, whereas Java-Script does not.
  • Java-Script has; a statement terminator, whereas Python has a newline.
  • Python is a better-designed language that makes it easy to maintain, whereas JavaScript is poor.
  • Python is not suitable for mobile development, whereas Java-Script is good.
  • Python is slow to run compared to JavaScript.
  • Python provides a huge standard library, whereas JavaScript has a limited standard library.
  • Python heavily relies on assignments with no difference between variables and assignments, whereas JavaScript doesn’t rely on.
  • Python has many libraries for scientific computing, data analytics, and machine learning, whereas JavaScript does not.
  • Python supports numeral data types like int, float, and fixed-point decimal, whereas Java-Script mainly works on floating-point variables.
  • Python has an inbuilt REPL, whereas JavaScript does not.
  • JavaScript runs on the browser and server, whereas Python is mainly used for server-side programming.
  • Python is easy to get started compared to JavaScript.
  • Python is easy to find new jobs compared to JavaScript this year.
  • Python object-based is nearly equal to JavaScript, and Python supports a programming style that uses simple functions and variables.
  • JavaScript is the most complex modern programming language compared to Python.
  • Python and JavaScript both use a lexical scope with slight differences.
  • Python has a Self-argument as the first argument for each method, whereas JavaScript accessed the object using “this.”
  • Unlike JavaScript, Python does not have a way to inherit from instances.
  • Python is suitable for data analytics, machine learning, or math-intensive operations. In contrast, JavaScript is suitable for building a website or native applications as it takes less time for UI work.

Comparison Table Between Python vs JavaScript

Following is the comparison table between Python vs JavaScript:

Basis for Comparison Python JavaScript
REPL(Read-Eval-Print-Loop) We will get it with Python installation and call different Python versions depending on our installation. Whereas for Java-Script, we didn’t have an inbuilt REPL as we usually 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, the source code is ASCII by default unless we specify any encoding format. Java-Script should be encoded as UTF-16 without 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, 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 a class-based inheritance model. Let us consider an example below:

class Welcome:
def __init__(self,name):
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 a prototype-based inheritance model. Let us consider an eple as below:

We need to create a function where we use classes in Python as below:

Welcome = function(name)
{
this.name=name
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 with exact parameters are not as by default; any missing parameter gets value as “undefined,” and any extra arguments end as particular arguments.
Data Types Python has two similar data, a types list, and a tuple. Python’s list and Java-Script array are quite similar. Java-Script has an inbuilt array type.
Properties and Attributes Python allows defining an attribute using descriptor protocol where we can use a getter and setter functions. Whereas Java-Script objects have properties that can be composed of underlying attributes, it lets you define a property.
Modules Python is a battery-included language with a wide range of modules. Whereas Java-Script comes with a few modules like date, math, regexp, and JSON, its functionality is available through the host environment like a web browser or some other environment.

Conclusion

Finally, it is an 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 minimal. You can do almost everything with Python and JavaScript as they share everyday 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 extensions to achieve whatever is needed. I felt that, hopefully, you would better understand these programming languages. If you want to suggest that one is better to learn first, I would recommend Python as it has a good market in the IT industry and is understand to learn.
