This article will discuss the critical differences between JavaScript vs. Python. These two programming languages have already paved their way into the minds and hearts of programmers all over the globe.

Let’s Have a Deep Insight on JavaScript

This scripting language is majorly employed to automate application and website processes. Originally this programming language was introduced as a front-end language to offer browsers high-powered functionality. Read more on different types of frameworks in Javascripts.

However, with the advent of Node.js in 2009 as a back-end language, developers could utilize JavaScript to code both the server and front-end side, augmenting its popularity. Businesses can empower themselves with JavaScript development services through value-adding applications.

Let’s Have a Deep Insight on Python

This is an object-oriented language. Programmers with this coding language can develop websites and applications by utilizing virtual building blocks objects. Python employs the object model to decrease complexity by offering programmers a non-fictional dynamic and clear structure.

☛ Key differences between JavaScript and Python

Here are a few critical points that portray the key differences between Python vs. JavaScript:

  • Python carries a new line, while JavaScript comes with a statement terminator.
  • When it comes to JavaScript vs. Python speed, the latter is slow compared to the former.
  • JavaScript uses “this” to access the object, whereas Python uses a self-argument as a primary argument for every method.
  • The question, JavaScript vs. Python, which is easier, frequently pops up. JavaScript is a highly complex contemporary programming language in comparison to Python. Starting with Python is recommended for beginners.
  • Python knows no way of inheriting with instances, whereas JavaScript knows.
  • JavaScript operates on the front-end, and Python functions on the server-side programming.
  • In terms of maintenance and design, Python wins the medal, and JavaScript doesn’t.
  • JavaScript is fantastic for mobile development, whereas Python isn’t.
  • Python comes with procedural programming, which is not the case with JavaScript.
  • JavaScript comprises a restricted standard library, and Python offers a massive standard library.
  • Python has several libraries for data analytics, machine learning, and scientific computing, but JavaScript has no libraries for these aspects.
  • JavaScript and Python both utilize a lexical scope with very few differences.

Comparisons Between JavaScript and Python

As per a report, the E-commerce industry will grow from 39.5 billion dollars in 2017 to 200 billion dollars by 2026. Coding is at an all-time high with E-commerce’s increasing importance and utilization. However, analytics specialists and software developers always find it challenging to choose between Python and JavaScript. This is because the scope of utilization for both languages is vast. Here we have penned down the most vital differences between the two programming languages. The difference between Python and JavaScript is clearly defined in this section.

☛ Mutability

  • JavaScript is a language that carries no concept of immutability and mutability.
  • Python comprises immutable and mutable data types, such as lists and sets.

☛ Numbers

  • There are just floating-point numbers in JavaScript.
  • There are numerous kinds, such as fixed-point decimal and in Python

☛ Code Blocks

  • JavaScript utilizes curly brackets.
  • Python utilizes indentation

☛ REPL or (Read-Eval-Print-Loop)

  • There is no in-built REPL in JavaScript as it mainly operates in a browser. However, one can use it with Node.js installation.
  • Using REPL is easy as it comes with Python installation itself.

☛ Strings

  • JavaScript must be encoded as UTF-16. There is no built-in support available for maneuvering raw bytes.
  • ASCII is the source code in Python, and it is by default. This difference between JavaScript and Python is notable.

☛ Hash Tables

  • A built-in hash table support is not available in JavaScript.
  • Python comes with built-in hash tables, known assets, and dictionaries that programmers can use in hashing with values and keys.

☛ Data Types

  • JavaScript comes with inherent array type.
  • Python comes with two kinds of similar data and tuple. Hence, no focus needs to be put on the difference between Python or JavaScript here as the array and list of JavaScript and Python, respectively, are pretty similar.

☛ Modules

  • A few modules are available in JavaScript, such as math, JSON, date, and regexp. This language carries the functionality accessible via a host environment such as a web browser.
  • Python is a language with batteries incorporated as there is a broad array of modules available.

☛ Scalability

  • JavaScript is thought-out for scalability. It provides support for asynchronous programming. It is a faster language as it is developed on Chrome’s V8. JavaScript is preferred for designing real-time applications.
  • Python is not known for supporting asynchronous programming. Instead, it favors co-routines that, in turn, favor asynchronous programming. So if you are questioning Python vs. JavaScript performance, learn that it is not as scalable as JavaScript, but it carries the tools for obtaining scalability.

☛ Versatility

  • Python is majorly used in Artificial Intelligence, Machine Learning, and data analytics.
  • JavaScript is more beneficial as it can be used both as a backend and front-end language. However, Python is majorly a backend language limited to the server-side.

☛ Job Opportunities

  • Currently, there are more than 67000 Python vacancies on leading job portals. Python job opportunities include software engineering, advanced data science, machine learning roles, quality assurance, etc.
  • There are more than 44000 JavaScript jobs on leading job portals. It also provides senior and junior roles for full-stack engineers, architects, and front-end developers.

☛ Real-World Applications

  • The versatility and power of Python have made it an indispensable tool in almost all scientific applications all over the globe. In addition, it is majorly utilized in specialized applications that include artificial intelligence, computer science education, data science, etc. It is even used for web development.
  • JavaScript is used for developing both the front-end and backend of a web application. As a result, users can observe and communicate with the front-end portion of an application.

☛ Syntax

  • Python describes code blocks by depending on indentation. When many continuous code lines are indented at a similar level, they also become a part of the parallel code block. This is used to define functions, loops, and conditionals.

  • On the contrary, JavaScript groups statements by using curly braces ({}) that belong to a similar code block.

☛ Writing Comments

Writing a comment calls for using a hashtag (#) in Python. The characters that are on the same line following this symbol are regarded as a portion of the comment. When it comes to JavaScript, two slashes (//) are used to write a single-line comment

Examples:

In Python:

# Comment

In JavaScript:

// Comment

☛ Input

  • The input () function is used in Python to request user input. The message is written within parentheses. The user receives a prompt to pass in a value within the console.
  • A small prompt is displayed in JavaScript with a window. Prompt (message) and the outcome is assigned to a variable.

☛ Output

  • A value is printed to the console in Python with the print () function. Thereby the value is passed within parentheses.
  • A value is printed to the console in JavaScript by using console.log () thereby; the value is passed within parentheses.

☛ Functions

  • Writing the keyword def is important in Python that is followed by the function’s name. The parameters list is written within parentheses. Following the list, a colon (:) and the function’s body are written.
  • The only difference in JavaScript is that the function keyword is used for describing a function. Curly braces surround the function’s body.

Conclusion

As we reach the end of the article, it is clear that the differences between JavaScript vs. Python are minimal. Professionals can do everything with both JavaScript and Python languages as these share common aspects such as imperative and functional programming, lexically scoped, interpreted programming, etc.
