Python vs JavaScript: Top Key Differences

Both Python and JavaScript have been at the top of their game as the best programming languages of this decade and the last one, too. But, each of these languages have their own usage and they work differently as well. This blog aims to cover all of these differences that lie in between these two programming languages as a whole. Read on.

On this Python vs JavaScript blog, we will take a look at these aspects:

What is Python?

Python is the world’s most popular language as of this decade, and it has been predicted that it will remain at the top for another decade at least. It is very powerful, and it offers highly readable syntax and helps developers in a lot of ways. This speaks volumes of the capability that Python offers. Python is a multi-paradigm programming language that provides complete support for a variety of programming paradigms.

Following are the paradigms that are supported by Python:

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

The main advantage of Python lies in the fact that it has thousands of libraries and modules that allow programmers to cater to a variety of problems and solve them easily. Be it offering different programming styles or implementing customized solutions, Python provides developers with numerous advantages. If you are looking for upskilling yourself in python you can do Python training in Bangalore.

Here’s a list of the most important benefits of using Python:

  • Easy to use and fast to develop
  • Open-source with a large community
  • Numerous libraries for all domains
  • Built to support rapid prototyping
  • Offers simplicity even in complex tasks

With the advantages that Python offers, it is clear that there are thousands of companies that make use of Python for their daily needs. Be it beginners, small start-ups, or established giants in the IT world, Python will fit in and be effective in any scenario.

Following are some of the famous companies that make use of Python:

  • Instagram
  • Google
  • Spotify
  • Netflix
  • Uber
  • Dropbox
  • Pinterest
  • Instacart
  • Reddit
  • Lyft

What is JavaScript?

JavaScript is one of the well-revered programming languages of the day as well. From its initial launch in 1995, it has shown nothing much immense progress to provide powerful programming concepts to developers.

From helping build dynamic web pages to providing functionality to add more features and supporting structures to already existing apps, the number of things JavaScript is good at is immeasurable.

Be it frontend development or backend development, JavaScript is plowing away at being the language that is tailor-made for Web Development in this decade. This calls on the nature of JavaScript to provide complete support for Full Stack Web Development.

There are many frameworks in JavaScript that are very popular, and the following are some of them:

Frontend Development:

  • ReactJS
  • VueJS
  • AngularJS
  • EmberJS
  • PreactJS
  • SvelteJS

Backend Development:

  • NuxtJS
  • GatsbyJS
  • NextJS
  • ExpressJS

Testing Frameworks:

  • Mocha
  • Jasmine
  • Jest

JavaScript is object-oriented, and this makes it very easy to implement dynamism when developing a website or a web application. The generic route of using HTML and CSS for this purpose would make it very complex and not efficient.

The support that JavaScript provides for the usage of regular expressions, text handling syntaxes, and working with standard applications is unbeaten.

It is this unbeaten nature of JavaScript, alongside its powerful implementation, that has helped JavaScript on its way to entering the biggest companies in the world:

  • Microsoft
  • PayPal
  • Netflix
  • Groupon
  • Uber
  • Facebook
  • Google
  • eBay
  • Walmart

Python vs JavaScript

When it comes to the comparison between Python and JavaScript, below are the most prominent differences between the two based on various factors:

Comparison FactorPythonJavaScript
Data TypesSupports the usage of both mutable (sets) and immutable data types (lists) and moreDoes not separate between the mutable and the immutable nature of data types
NumbersSupports different numerics such as int, float, decimals, etc. to handle a variety of numerical dataSupports only the usage of floating-point numbers to handle the numerical data
Hash TablesSupports the usage of hash tables via sets and dictionaries to create key-value pairsDoes not offer any sort of native support for hashing functions or hash table creations
Code BlocksKnown for its usage of indentation to define code blocks and sub-level entitiesMakes use of ‘{ }’ to define code blocks and ‘;’ as a statement terminator
Implicit Data ConversionA strongly-typed programming language, i.e., there is no support for implicit data type conversionsA weakly-typed language and hence offers and supports implicit data type conversations
Function ArgumentsAlways raises an exception if any function that has incorrect parameters is calledDefaults all of its parameters as undefined; hence, it does not need to check for the presence of the exact parameter
Inheritance ModelUses the class-based inheritance model to function effectivelyUses the prototype-based inheritance model to function
Object AccessUses methods; and in every method, the first argument is always the self-argumentUses the ‘this’ method to access an object
Key ApplicationIdeal for data-intensive operations viz. Machine Learning, Deep Learning, and Data AnalyticsWell known and efficient in helping build elegant web applications and dynamic websites
Ease of LearningOffers better readability in terms of code and shorter syntax that make it easier for learnersUses native syntax that doesn’t offer as much readability or conciseness as Python

Python or JavaScript, which is the ultimate programming language? I am pretty sure you would’ve realized that this would be a difficult question to answer considering all of the above points.

To further add on, Python has been nothing but extremely effective in almost every field in the world of powerful computing. JavaScript, on the other hand, offers amazing new features to build native applications and websites, thereby making it a necessity for all.

The differences between these programming languages are becoming minimal as days pass by because everything that can be done in JavaScript can now be done in Python and vice versa.
