What are the differences between Django and the MEN of MERN stack?

I want to learn a back-end programming language and am debating between Django and the MEN of MERN stack. I am already familiar with React.js.

The main difference between Django and the MEN of MERN stack is that Django is a full-stack web framework while the MEN of MERN stack is a collection of technologies used for web development (MongoDB, Express.js, React.js, and Node.js). While both can be used to build web applications, Django is more opinionated and provides more out-of-the-box features, while the MEN of MERN stack is more flexible and allows for more customization.
