Python vs. JavaScript: Key Differences

Syntax and Readability

Python’s clean, English-like syntax makes it ideal for beginners. Indentation-based blocks (no curly braces!) reduce clutter. JavaScript’s syntax is more flexible but requires semicolons and brackets, which can confuse newcomers.

Example:

# Python

if 5 > 2:

    print(“Python is simple!”)

// JavaScript

if (5 > 2) {

    console.log(“JS needs brackets!”);

}

Use Cases and Applications

Python dominates data science, AI, and backend development (thanks to Django/Flask). JavaScript rules web development (React, Node.js) and mobile apps (React Native).

Performance and Speed

JavaScript’s V8 engine (Chrome, Node.js) offers faster execution for web tasks. Python struggles with speed but shines in prototyping. For heavy computations, Python uses C-extensions (NumPy) to close the gap.

Stat:

Python is ~2–10x slower than JavaScript in runtime benchmarks (Source: TechEmpower, 2023).
