Python and JavaScript. Why are used as wrappers?

2 min readJul 25, 2024

Today I won't make you a fool by telling you some advantages of Python and JavaScript, Instead, I’ll tell you why these languages are used more often rather than other popular languages.

Let’s break it down in simple terms and see what makes them stand out.

Why Python and JavaScript Are So Popular

Python and JavaScript are everywhere these days. You’ll find them in web development, data science, machine learning, and more. But why are these two languages so widely used? Let’s break it down in simple terms and see what makes them stand out.

How Do They Work?

Let’s look at some popular tools and libraries built with Python and JavaScript to understand better:

1. Node.js

What It Is: Node.js is a way to run JavaScript on the server side.
How It Works: It uses Google’s V8 JavaScript engine for fast performance. Behind the scenes, Node.js is powered by C++ which helps it talk to the operating system and handle tasks efficiently.

2. TensorFlow

What It Is: TensorFlow is a library for building machine learning models.
How It Works: TensorFlow uses Python for most tasks because Python is easy to write and understand. But the heavy lifting is done in C++, which makes the calculations fast.

3. PyTorch

What It Is: PyTorch is another library for machine learning, known for its ease of use.
How It Works: Like TensorFlow, PyTorch uses Python for the user-friendly parts. Its core operations are handled by C++ for better performance.

4. Pandas

What It Is: Pandas is a library for working with data in Python .
How It Works: Pandas relies on NumPy for fast numerical calculations. NumPy itself is built on C, which makes data operations quick and efficient.

5. NumPy

What It Is: NumPy is a fundamental library for numerical computing in Python.
How It Works: NumPy’s core is written in C and Fortran, which means it can perform complex calculations rapidly. Python acts as the friendly interface for these powerful computations.

Why Python and JavaScript?

1. Ease of Use

Both languages are designed to be simple and intuitive. This makes it easier for developers to write and understand code. Whether you’re doing data analysis or building a website, Python and JavaScript make it straightforward.

2. Integration with Fast Languages

Python and JavaScript act as wrappers around lower-level languages like C and C++. This means developers can use Python or JavaScript to build applications quickly, while still benefiting from the speed and efficiency of C and C++.

3. Rapid Development

With extensive libraries and frameworks available, both Python and JavaScript allow for quick development and testing. This makes it possible to build and improve features at a fast pace.

Real-World Impact

The popularity of Python and JavaScript isn’t just because of their ease of use. It’s also due to their ability to handle complex tasks efficiently by leveraging powerful underlying technologies. This combination of user-friendly interfaces and high performance is why these languages are so popular and widely adopted.
