NodeJS or Python: Which Backend Technology is Best Suited in 2024?

With the increase in backend frameworks, it became too difficult for developers to choose what to use and for which scenarios should we use those.

It is especially difficult to choose between NodeJS or Python, two of the popular backend technologies out there. While each of them has its specific set of benefits, let us understand, overall, which is better to use, NodeJS or Python.

In this article, you are going to learn about each of these technologies in detail and understand whether NodeJS or Python is better for backend work.

So, without further ado, let’s get started.

Understanding NodeJS

To help you understand which is better among the two, NodeJS or Python, we divided the section in such a way that first you’ll be learning about both of these languages and then at the end, you’ll be seeing whether NodeJS or Python is better.

Imagine you’re at a crowded coffee shop. In this coffee shop, every worker can handle only one customer at a time, from taking the order to making the coffee and then moving on to the next customer.

This is how traditional servers work; they can only handle one request at a time before moving on to the next. Now, if this coffee shop gets too busy, customers will have to wait a long time for their orders.

Enter Node.js, which flips this scenario altogether. Node.js is like a super-efficient coffee shop where each worker can start making a coffee, and while the coffee is brewing (a task that doesn’t need the worker’s constant attention), they can take another order, start making another coffee, and so on.

This is possible because Node.js operates on a non-blocking, event-driven model. This means it can handle many requests at the same time without waiting for each one to finish before starting the next.

It’s designed to be fast and efficient, especially for tasks that involve a lot of waiting, such as fetching data from another server or querying a database.

So, how does Node.js manage to do this? Well, it uses something called the “event loop.” You can think of the event loop as a to-do list that Node.js keeps checking. Whenever it finishes a task, it looks at this list to see if there’s anything else that needs to be done. This way, Node.js can quickly switch between tasks, making it incredibly efficient at handling multiple requests simultaneously.

Another key point about Node.js is that it uses JavaScript. JavaScript is a language many people already use to make websites interactive. By using JavaScript on the server side as well, developers can write both the client-side and server-side code in the same language.

Understanding Python

Moving on in our quest to find which is better, NodeJS or Python, we’ve arrived at our next stop where we understand in-depth Python programming.

Imagine you’ve decided to learn to cook. You’ve never boiled water, let alone prepared a meal. Where do you start? With a cookbook written in straightforward, easy-to-understand language, right? That’s Python in the world of programming.

It’s like the friendly cookbook that doesn’t scare you away with complex jargon on your first day in the kitchen. Instead, it welcomes you with simple instructions that make sense even at first glance.

Python is a popular programming language known for its clear, readable style. It’s kind of like English; you write instructions that the computer understands and executes. Because of this simplicity, it’s often the first language people learn when they dive into coding.

You can use Python to do all sorts of things: build websites, analyze data, automate boring tasks, and even delve into artificial intelligence.

One of Python’s biggest strengths is its community. Imagine moving to a new town and finding out that everyone is eager to help you settle in. Got a question? Someone’s there to answer it. Stuck on a problem? There’s likely a friendly neighbor who’s solved it before. This supportive environment makes learning and working with Python not just easier but also enjoyable.

So, if you’re curious about coding but worried it’s too complex, think of Python. It’s your friendly guide into the world of programming, making sure you don’t get lost in the technicalities.

NodeJS or Python: What to Choose for Your Project?

Now that you’ve seen all the prerequisites needed to understand which is better, NodeJS or Python, let us now address the main topic and see which is better for your project, NodeJS or Python.

Before you go further, remember that both of these languages are strong in their way so we can’t say that one is better than the other rather what we can say is when to use what as they are powerful in certain circumstances.

Let’s delve deeper into each aspect of choosing between Node.js or Python, focusing on what’s most important for you and your project.

When to Choose NodeJS?

In the batter between NodeJS and Python, let us first see when to use NodeJS:

1. Real-Time Applications:

If you’re building real-time applications such as chat apps, live notifications, or online gaming interfaces, NodeJS is a strong contender. Its event-driven architecture is designed to handle asynchronous operations, making it adept at managing multiple connections simultaneously.

This means that for applications requiring instant updates or interactions, Node.js ensures quick, efficient processing without the bog-down of server requests.

2. Full Stack Development with JavaScript:

If you or your team are already comfortable with JavaScript for front-end development, choosing Node.js for the backend can streamline your development process.

Using JavaScript on both the front and back ends of your application simplifies development, as you’re working with the same language and potentially similar libraries or frameworks across the entire project. This can lead to faster development cycles and easier maintenance.

3. Building APIs:

Node.js is also great for developing RESTful APIs (Application Programming Interfaces) that allow your applications to communicate with other software.

Its ability to handle a large number of connections with low latency makes it ideal for services where you need to connect to databases or other services and deliver data efficiently to users.

When to Choose Python?

Let us see about Python in our updated quest to find when to use what, NodeJS or Python:

1. Data Science and Machine Learning:

Python is the go-to language for data science, machine learning, and artificial intelligence projects. This is thanks to its rich ecosystem of data-focused libraries like NumPy, pandas, and scikit-learn, as well as powerful frameworks for AI such as TensorFlow and PyTorch.

If your project involves data analysis, predictive modeling, or any form of AI, Python provides the tools and libraries to get the job done effectively and efficiently.

2. Rapid Development and Prototyping:

Python’s syntax is designed for readability and simplicity, making it an excellent choice for quickly developing prototypes or projects where development speed is a priority.

With frameworks like Django and Flask, you can set up a robust web application or API quickly, allowing more time to focus on your application’s features rather than boilerplate code.

3. Educational, Scientific, and Numeric Computing:

Python is widely used in academic and scientific research because of its simplicity and the vast array of libraries available for numeric and scientific computing, such as SciPy and Matplotlib.

If your project involves complex mathematical calculations, statistical analysis, or graphical representations of data, Python’s ecosystem has the tools to support these requirements.

To put it simply, choosing between NodeJS or Python comes down to the specific needs of your project and your personal or team’s proficiency with the technologies.

• Opt for NodeJS if you’re developing real-time applications, need to work within a JavaScript stack, or are focusing on building scalable network applications and APIs.
• Choose Python if your project revolves around data science, or machine learning, or requires rapid development with a focus on readability and ease of use.

As we said earlier, there is no one answer to the question, NodeJS or Python, it is evident that both of them are strong in certain aspects and it is important to embrace them both to become a better full-stack developer.
