In this article, we will know about Javascript & Python, the purpose of their usage, along with knowing the difference between them. 

Python: Python is a high-level general-purpose programming language that was developed to emphasize code readability and allow them to work quickly and efficiently. Python is used for web applications, Game Development, Machine Learning, and Artificial Intelligence.

Example: This is a simple Python program to print “Hello World”.

Python3




# Python program to print 'Hello world'
print("Hello World")


Output:

Hello World

Usage of Python in various domains

Benefits of Python:

  1. It is a high-level Object-oriented language having user-friendly data structures.
  2. Open source and community development.
  3. It is versatile, easy to read, learn and write.
  4. It supports an extensive range of libraries(NumPy for numerical calculations, Pandas for data analytics, etc).
  5. It is a dynamically typed language ie., there is no need to mention data type based on the value assigned, it takes data type.
  6. Ideal for prototypes – provide more functionality with less coding
  7. Highly Efficient(Python’s clean object-oriented design provides enhanced process control, and the language is equipped with excellent text processing and integration capabilities, as well as its own unit testing framework, which makes it more efficient.)

JavaScript: JavaScript is a programming language that conforms to the ECMAScript specification. It is a high-level scripting language introduced by Netscape to be run on the client-side of the web browser. It can insert dynamic text into HTML. JavaScript is also known as the browser’s language.

Example: This is a simple program that will print “Hello World” using Javascript.

Javascript




// JavaScript program to print 'Hello world'
  
<script> 
console.log('Hello World'); 
</script>


Output:

"Hello World"

Usage of the Javascript in various domains

Benefits of Javascript:

  1. JavaScript has the ability to support all modern browsers and produce an equivalent result.
  2. Global companies support community development by creating projects that are important. An example is Google (created Angular framework) or Facebook (created the React.js framework).
  3. Regardless of where you host JavaScript, it always gets executed on the client environment to save lots of bandwidth and make the execution process fast.
  4. In JavaScript, XMLHttpRequest is an important object that was designed by Microsoft. The object calls made by XMLHttpRequest as an asynchronous HTTP request to the server to transfer the data to both sides without reloading the page.

Difference between Python and JavaScript: There are significant differences for both of them, which are discussed below:

S.no.

Python

Javascript

1.

Python is a high-level general-purpose interpreted programming language that was developed to emphasize code readability.

JavaScript is a programming language that conforms to the ECMAScript specification.

2.

It is a scripting language used for developing both desktop and web applications.

It is a client-side scripting language.

3.

It uses a class-based inheritance model.

It uses a prototype-based inheritance model.

4.

In this, an exception is raised when the function is called with the wrong parameters.

It does not care about the functions are called with correct parameters or not.

5.

List, set, and dict are mutable while int, tuple, bool, Unicode are immutable in python.

In JavaScript, only objects and arrays are mutable.

6.

It uses a more conservative programming paradigm similar to C, C++, and Java.

It is a language of the web browser and one of the easiest to use.

7.

It has a comprehensive standard library.

It has a limited set of utility objects.
