How do you assess your skills in working with the Node.js platform?

My skills with Node.js are at a junior/middle level. I can create servers using Express, work with asynchronous code through promises and async/await, interact with databases (for example, MongoDB), and configure middleware. I am also familiar with the basics of working with streams and error handling in Node.js.

Example of a simple server on Express:

const express = require('express');
const app = express();

app.get('/', async (req, res) => {
  res.send('Hello, Node.js!');
});

app.listen(3000, () => {
  console.log('Server started on port 3000');
});
