Python Vs JavaScript: Key Differences A Programmer Should Know

Nowadays, both Python and JavaScript are becoming popular programming languages. In fact, Every programmer and non-programmer wants to learn both languages. In addition, Both programming languages hold great career opportunities. But several programmers, especially beginners, are not aware of Python vs JavaScript. As a result, They do not know the main difference between them. If you are also one of them, this blog will be helpful for you.

In this blog, we will learn Python vs JavaScript. in addition to We will learn the key difference between both of them. But before that, we will discuss the overview of both, Python vs JavaScript.

Python vs JavaScript: Overview

Python vs JavaScript is both high-level interpreted programming languages. And, these languages design to be simple to understand and use. furthermore, It is a scripting language similar to Perl/Ruby. It also utilizes to build web apps.

The object-oriented programming language Java-Script was established in the ECMAScript language specification. It enables you to build pages of a dynamic web. JS supports Object-oriented, functional, and imperative programming.

What is Python?

Python supports Object-oriented programming, functional programming, imperative programming, and procedural programming. In fact, It came up with a variety of pre-installed modules and packages. It lets programmers create programs in a variety of styles, both simple and complex.

Features Of Python

Following are some of the features of the Python programming language;

  • Python is a simple language to learn, read, and understand.
  • It can run on a different kind of hardware system. It has a consistent user interface.
  • Also, Python’s structure is suitable for huge programs.
  • Python has built-in support for garbage collection.
  • It allows dynamic type testing and has high-level dynamic data types.
  • The Python programming language is use in connection with Java, C, and C++ code.

What is JavaScript?

JS is an object-oriented programming language. Javascript is widely utilizes in browsers to give dynamic functionality. It is impossible to create with standard HTML and CSS. JS supports text, regular expressions, and dates in common applications.

Features Of JavaScript

Following are some features of JavaScript. Let’s take a look;

  • It’s a cross-platform programming language.
  • It is commonly used on both the client and server sides.
  • Workflow for Effective Testing
  • It is simple to learn and start coding with.
  • Provides additional repercussions

Python vs Javascript: Main Difference

Read-Eval-Print-Loop (REPL)

Python: We have to install Python. We will use different Python versions depending on our setup.

Javascript: We did not have an inbuilt REPL for Java-Script. as well as, it is generally uses in a browser. However, by installing node.js, we may use REPL.

Mutability

Python: Set (changeable) and list (immutable) are the types in Python (Immutable).

Javascript: Java-Script has no concept of mutable and immutable variables.

Strings

Python: Python’s source code is ASCII by default.

JavaScript: Java-Script should be encoded in UTF-16. It does not have built-in functionality for handling raw bytes.

Numbers

Python: Different numeric types exist in Python. Like int, fixed-point decimal, float, etc.

JavaScript: Java-Script is limited to floating-point numbers.

Code Blocks

Python: Python uses indentation for code blocks.

JavaScript: JS uses curly brackets.

Function Argument

Python: When a function is called with improper parameters, Python throws an error. And it accepts some additional parameter passing syntax.

JavaScript: Java-Script doesn’t mind if functions aren’t called with precise parameters. Because any missing parameter is consider as “undefine” by default. as a result, any other arguments is treat as special arguments.

Data Types

Python: Python contains two data types that are comparable to each other: list and tuple. The list in Python and the array in Java-Script are quite similar.

Javascript: The array type in Java-Script is built-in.

Attributes and Properties

Python: We can utilize getter and setter methods to define an attribute in Python.

JavaScript: Java-Script objects contain properties that may be made up of underlying attributes. It enables you to identify a property.

Modules

Python: Python describes itself as a “batteries included” language. It involves a huge number of modules.

JavaScript: Java-Script comes with only a few modules. Such as date, arithmetic, regexp, and JSON. as a result, its capability is access through the host environment. Such as a web browser, etc.

Hash Tables

Python: Python includes built-in hash tables. Such as dictionaries, sets, etc. And, It may be uses to store keys and values in a hash.

JavaScript: Java-Script has no built-in support for hash tables.

Scope

Python: Python is an excellent choice for data analytics, machine learning, and other math-intensive jobs.

Javascript: JavaScript is an excellent choice for creating a website or native app.

Python vs JavaScript: Applications

Python Applications

  • Language for Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL)
  • Web scripting for rapid prototyping
  • Used in graphical user interface applications.
  • Applications that use databases
  • Scientific applications

JavaScript Applications

  • It allows you to build scalable and secure apps.
  • Single-Page Dynamic Applications (SPAs)
  • JavaScript is uses in front-end technologies. Such as jQuery, AngularJS, Ember.js, and ReactJS.
  • Server-side technologies are based on JS. Such as MongoDB, Node.js, and Express.js.
  • It may also be used to create mobile apps using React, PhoneGap, and more.

BONUS POINT

When to use Python and JavaScript?

  • When it comes to web development, HTML, CSS, and JavaScript all are the best options.
  • If people want to learn Machine learning, data science, and neural networks. Then learn Python.
  • Transpilers that modify Python code to JavaScript create apps slower. Therefore Python may be used as a frontend language. As a result, it is preferable to utilize Python for backend development and JavaScript for frontend development.

Conclusion

To sum up, we have learned about Python vs JavaScript. We have discussed the main difference between them. Both programming languages also share some similarities. Like both follow a multi-paradigm approach and are lexically scoped. But there are still differences between them that can not be ignored. So, in the end, I hope the Python vs JavaScript blog helps you in your learning.
