Python vs JavaScript: Difference Between Python and JS

Introduction

JavaScript and Python are all prevailing programming languages. These programming languages have a broad range of use in the real world. JavaScript is mainly used for making front-end & rear-end web & mobile application development. Moreover, Python language is majorly used for creating web & scientific research. However, both of these programming languages are object-oriented and their scopes are dissimilar. The 2 programming languages have more in common.

What’s Python?

Python programing language is a high-level, interpreted, and strongly-typed programming language. It features object-oriented design and dynamic semantics. It’s meant to be simple to read and implement. Moreover, the Python programing language has an in-built data structure that has dynamic typing & dynamic binding at a great level.

Python language serves as a scripting language for Perl & Ruby for making web applications. It connects existing components & helps in creating Rapid Applications. Python enables programmers to utilize a range of programming kinds for making complex and simple programs.

Python programming language interpreter and the strong normal library are open to utilize & share in binary kind or source to all major platforms.

Python language was 1st made in the late 80s. It was developed through Guido-van Rossum & launched back in 1991. Python is an improved open-source language for programing which facilitates public debate through PEPs (Python-Enhancement Proposals). Programming paradigms that are supported by Python include:

  • Imperative programming
  • Functional programming
  • Object-oriented programming
  • Procedural programming

Advantages of Python

  • Has a simple syntax compared to C, C++ & Java languages
  • Has a different prebuilt library which makes development easy.
  • Has pre-installed shell.
  • Operates on numerous kinds of computers and operating systems like macOS, Windows, & Linux.
  • Have extensive library & handy necessity for developers.
  • Includes interactive shell which enables us in evaluating products before they’re implemented.
  • Arrives with a more standard library that supports a broad variety of normal programming jobs.
  • Python is an object-oriented language for programming that’s utilized in developing fast applications.

Disadvantages

  • Python is dynamic thus it generates extra errors in execution.
  • Python is weak with mobile computing, thus it’s not utilized in application development.
  • It is just utilized on scarce platforms.
  • Python is a below-developed & basic layer of database access.
  • Has no commercial support.

Python Interview Questions


What’s JavaScript?

This is an object-oriented language for programming. It’s more utilized in browsers to offer dynamic functionality that can’t be achieved via normal CSS & HTML. JavaScript has support for normal apps with regular expressions, dates, and text. JavaScript is used in building dynamic HTML sites which have interactive belongings on web pages. Furthermore, JavaScript is commonly utilized in mobile application development and game development.

This interpreted scripting programing language and code can just be executed & run in the browser. Node.js is used in executing & running the code without the browser. JavaScript is utilized for both server-side & development of client-side.

Brendan Eich made JavaScript & was 1st published back in 1995. JavaScript language was first understood as LiveScript earlier it was renamed JavaScript. The syntax is deeply influenced by the C programming language. JavaScript filename has an extension of .js.

Advantages of JavaScript

  • Operates on any browser
  • Used on server-side & client-side
  • Enables cross-compilation
  • It’s open-source
  • JavaScript can be used for writing bigger applications
  • Enables one in building interfaces which react whenever clients hover mouse on them.
  • Supports modules, classes & interfaces

Disadvantages of JavaScript language

  • JavaScript client-side does not support reading or writing files. It’s only for keeping security
  • Can’t be utilized in developing networking apps. Has no support to networking applications
  • JavaScript supports just single inheritance & not several inheritances

Major differences between JavaScript and Python language

  • Python is object-based programming that’s the same as JavaScript & supports programming kinds that utilize the basic variables and functions.
  • Python has a good-designed language that’s simpler to maintain compared to JavaScript language.
  • Python is more typed, minus implicit kind conversions, where JavaScript is faintly typed.
  • Python language is compatible with a broad variety of numerical information kinds, including float, int, & fixed decimal points. With Java-Script more deals have floating variables points.
  • Python utilizes Self-argument like 1st argument to every role, while JavaScript utilizes the “this” function in accessing the object.
  • Python comes with libraries number for data analytics, machine learning & scientific computing while with JavaScript it doesn’t have.
  • JavaScript is asynchronous & blocking programming that’s common. With Python language, it’s default through de-facto.
  • Python language is majorly utilized for programming the server-side, JavaScript operates on server & browser.
  • Python language executes the program slowly compared to JavaScript language.
  • Python is simple to begin programming compared to JavaScript language.
  • JavaScript language utilizes a “;” as terminator statement while Python language doesn’t.
  • Python language doesn’t enable instances inheritance, unlike JavaScript.
  • JavaScript language is suitable for mobile app development, while Python language isn’t good.

JavaScript & Python head-to-head comparison

Strings

Automatic python source code is ASCII not unless the encoding format is defined. JavaScript language needs UTF-16 encoding, & there’s no in-built support that manipulates raw bytes.

Properties & Attributes

In Python language getter & setter functions are used in defining features in Python with the help of descriptor protocol. With JavaScript, objects need properties that may be a build-up of underlying attributes & enables one to state property.

Numbers

With Python, one uses several numeric kinds like int, float, fixed-point decimal, etc. JavaScript language supports just floating-point numbers.

Function Arguments

When the function is known using invalid restrictions, Python throws an exception & accepts extra parameters passing the syntax. With Java-Script it does not care if the functions are not called using the exact parameters the reason being every missing limit is treated like “undefined” via default, & every extra argument is treated like special arguments.

Read-Eval-Print-Loop (REPL)

We will receive it when Python is installed, & we will use various Python versions that depend on the setup. With Java-Script it is majorly utilized in browsers. It doesn’t have an in-built REPL. Moreover, REPL can be utilized by installing node.js.

Hash Tables

Python has in-built hash-tables same as collections, dictionaries & others which may be utilized in storing keys & values at the hash. JavaScript language has no in-built support to hash tables.

Modules

Python is it arrives with a language with included battery. This is because it arrives with a big modules number. JavaScript language comes with only little modules which include math, date, regexp & JSON. Additionally, it has a purpose that’s available through the host environment, like a browser.

Mutability

Python includes all mutable & immutable data kinds. These include set & list. JavaScript language has no information kind like immutable and mutable.

Data kinds

Python has 2 data kinds which are the same as every other including list & tuple. JavaScript array & Python’s list are similar. JavaScript language has an in-built array kind.

Mobile Development

Python isn’t a reasonable choice for developing mobile applications. JavaScript language is the best selection for mobile application development. It’s also good for back-end & front-end development.

Code Blocks

Python utilizes indentation while JavaScript utilizes curly brackets.

Scope

Python language is the best choice for data analytics, machine learning, and math-intensive operations. JavaScript language is best for developing a native application or website.

Object Access

Python language 1st argument for every approach is self-argument. With JavaScript, it utilizes the ‘this’ way for object access.

Inheritance

Python utilizes a class-based inheritance model. JavaScript utilizes a prototype-based inheritance model

Conclusion

To sum up, every language is simple to use and their difference is very small. With python, one can do almost everything that can be done with JavaScript. Python is used for developing a wide range of the app, scientific purposes, and web development. JavaScript language is majorly used in mobile application development and web development.
