Choosing Between JavaScript and Python: What to Learn in 2024
Written on
Chapter 1: Popularity of JavaScript and Python
According to the 2023 Stack Overflow survey, JavaScript reigns as the most utilized programming language, with 63.61% of developers employing it, while Python follows closely with 49.28%. Among professional developers, JavaScript maintains its leading position. For a more detailed analysis of the survey, you can check it out here.
A Comparative Overview
Both languages are highly favored, making it challenging to decide which one to learn first. In this section, we'll delve into specific aspects of each language to determine which might be a better fit for new learners. We will evaluate:
- Ease of learning
- Applications
- Libraries and frameworks
- Programming paradigms
- Syntax
Section 1.1: Ease of Learning
When selecting a programming language, the primary consideration is often its learnability. Factors such as syntax complexity, available resources, and community support play a significant role in determining how easy it is to grasp.
Python boasts a syntax that closely resembles English, utilizing logical operators as words (e.g., not, and, or), which makes it quite intuitive. For instance, to check for an element using a flag, you might write a conditional like, “if not found.”
Additionally, Python's use of indentation and colons for structuring code enhances readability.
In contrast, while JavaScript's syntax is also somewhat English-like, it incorporates more symbols. For instance, instead of using words like "and" or "or," JavaScript requires symbols like && and ||. This reliance on punctuation can render JavaScript less readable and potentially more challenging for complete beginners.
Both languages benefit from extensive online resources and a vibrant community presence across platforms like Stack Overflow and Twitter. As the most widely used language, JavaScript naturally enjoys a larger community.
In summary, Python is generally easier to learn from a syntax perspective, while JavaScript provides a wealth of online help.
Section 1.2: Applications
Both Python and JavaScript are versatile languages, facilitating higher-level programming. Many software development positions require knowledge of either language, with JavaScript being essential for web development.
The 2023 Stack Overflow survey indicated that 65.82% of professional developers utilize JavaScript, making it the predominant language in the field. Moreover, JavaScript is frequently cited as the most sought-after skill by employers, with over 60,000 jobs listed in the UK and an average salary of $108,981 for JavaScript developers in the US (according to Indeed).
JavaScript excels in web application development, while Python's applicability spans multiple domains, including Machine Learning, Artificial Intelligence, and Mathematical Modeling, enhancing its appeal across various fields.
Chapter 2: Libraries and Frameworks
After mastering the basics of Python and JavaScript, the next crucial step is leveraging external libraries to elevate your programming capabilities.
Python offers a rich selection of powerful libraries, contributing to its popularity. Notable libraries include NumPy, SciKit-learn, and Flask. NumPy enhances Python's functionality with built-in features for complex mathematical tasks, while SciKit-learn is a key player in enabling Machine Learning. Flask allows developers to create web page backends using Python.
The introduction of Node.js revolutionized JavaScript, allowing it to function beyond browsers and enabling server-side development. JavaScript's strong presence in web development is supported by a vast community, leading to the creation of numerous packages. As of September 2022, the npm registry boasted over 2.1 million packages, solidifying its status as the largest code repository for a single language.
Among the popular JavaScript frameworks, React and Vue stand out, simplifying web development by managing state and data effectively, which is crucial for large-scale applications.
While Python has a commendable selection of external tools, JavaScript typically offers a broader array. Therefore, if you opt for JavaScript, you will likely find a library or framework that meets your needs more readily.
Chapter 3: Programming Paradigms
A programming paradigm refers to a style or approach to writing code. Both Python and JavaScript are multi-paradigm languages, supporting various programming styles, including imperative, object-oriented, functional, and scripting paradigms.
Imperative Programming: This style involves writing code as a sequence of instructions, making it the most intuitive for beginners.
Object-Oriented Programming (OOP): In this paradigm, code is structured around "objects" that encapsulate properties and methods. Python's syntax for OOP is neat and closely aligns with formal definitions, while JavaScript’s syntax is less intuitive but excels in event-based programming.
Functional Programming: Both languages can support this paradigm, but JavaScript's ES6 features, such as const and arrow functions, have made functional programming more accessible.
Overall, Python's syntax is cleaner and more readable, making it easier for newcomers to understand basic concepts. Conversely, JavaScript's syntax may prepare learners for transitioning to other languages like Java or C++.
Conclusion
In conclusion, both Python and JavaScript offer valuable learning experiences, each with its advantages. Ultimately, if you aim to pursue a career in software development or already have a background in another language, JavaScript is recommended as a starting point.
