Python Vs Javascript — Guide with Examples

function greet(name) {
  console.log(`Hello, ${name}!`);
}

greet('John');

Hello, John!

Ah, the age-old debate: Python vs JavaScript. As a developer who's worked with both, I honestly prefer one over the other — but that's not what this article is about. Today, we're going to put these two languages side by side and explore their differences.

Similarities First

Before we dive into the differences, let's take a look at some similarities between Python and JavaScript. Both are:

High-level languages
Interpreted (no compilation needed)
Object-oriented
Extensively used in web development

Different Syntax

One of the most noticeable differences between Python and JavaScript is their syntax. Let's look at a simple "Hello World" example in both languages:

print("Hello, World!")

Hello, World!

console.log("Hello, World!");

Hello, World!

And here's an example of a for loop in both languages:

fruits = ['apple', 'banana', 'cherry']
for fruit in fruits:
  print(fruit)

apple banana cherry

const fruits = ['apple', 'banana', 'cherry'];
for (let i = 0; i < fruits.length; i++) {
  console.log(fruits[i]);
}

apple banana cherry

Type Checking

Another significant difference between Python and JavaScript is type checking. Python is dynamically typed, which means it checks the type of a variable at runtime. JavaScript is also dynamically typed, but it has some quirks:

let x = 5;
x = 'hello';
console.log(x); // outputs "hello"

hello

In contrast, Python will raise an error if you try to perform an operation on a variable with the wrong type:

x = 5
x = x + 'hello'
print(x)

TypeError: unsupported operand type(s) for +: 'int' and 'str'

Libraries and Frameworks

Both Python and JavaScript have extensive libraries and frameworks that make development easier. For example, Python has NumPy and pandas for data science, while JavaScript has React and Angular for front-end development.

If you've debugged a tricky issue at 2am, you know how important it is to have good documentation and community support. Both Python and JavaScript have excellent resources available.

Conclusion — or is it?

So, which one should you choose? Well, that depends on your project requirements and personal preferences. Call me old-fashioned but I still prefer writing back-end code in Python.
