Node.js

What is Node.js, really?

Node.js is JavaScript that runs outside the browser, on servers. The huge advantage is using one language for your entire stack — same code, same skills, same hires. Netflix, PayPal, LinkedIn, and Uber all moved key services to Node.js for the speed gains.

Why learn it in 2026?

Almost every modern startup hires "MERN stack" developers — MongoDB, Express, React, Node. Knowing Node opens you up to the entire JavaScript-based job market. Combine with React and you can charge for full-stack work.

What it looks like

// Express API endpoint
const express = require('express');
const app = express();

app.get('/users/:id', async (req, res) => {
    const user = await db.users.findById(req.params.id);
    res.json(user);
});
