I recommend flask because it is easier to master and to use .
The problem with nodejs is that you also have to express js because it is the backend framework while nodejs is basically a run time environment for your backend.

If you want to learn a language in one week and build a simple backend with authentication and data handling in the next, Python is the best choice because it’s easy to learn quickly and has frameworks like Flask or FastAPI that let you build backend apps fast with built-in support for auth and databases, making it ideal for simple apps within a short time

if you want stable enterprise backend applications .I suggest java.

JavaScript is the best.
Use Node.js for the Runtime.
Use Express.js for backend framework ☘️

🔥 Quick Answer for 2025 (2-week plan):
Go with Python + FastAPI. It’s the fastest to learn, super clean for beginners, and production-ready even at scale.




🧠 Final Thoughts
If your goal is:
✅ Simple auth + data backend
⏱️ Fast to learn
🧩 Easy to deploy
🎯 Real-world usable
Then Python + FastAPI is the smartest call right now.

I strongly recommend learning JavaScript or Python. Start by understanding the basic syntax of a programming language. Then, learn how APIs work and choose a framework such as Express (for JavaScript) or FastAPI (for Python).
