[Fixed] node index.js returning "Unexpected token >"


I have been doing javascript for a while and decided to start node.js.
I am running node.js and express on a raspberry pi (but I doubt this is the root of the problem).
I am making a chat app with socket.io, and the instructions said to create a package.json:

  "name": "socket-chat-example",
  "version": "0.0.1",
  "description": "my first socket.io app",
  "dependencies": {}

Then I ran the command npm install [email protected].
After that, I made an index.js file.
This is the code.

const app = require('express')();
const http = require('http').createServer(app);

app.get('/', (req, res) => {
  res.send('<h1>Hello world</h1>');

http.listen(3000, () => {
  console.log('listening on *:3000');

Error code:

app.get('/', (req, res) => {

Arrow functions are an ES2015 feature. Generally, environments after 2015 support arrow functions (and other modern syntax). Node 0.10.29 was released in 2014.

To fix it, install the latest long-term version that your machine supports: probably 14.6.0. See here.

Uninstall Node with

sudo apt remove nodejs

and then install it (which will fetch the latest version)

sudo apt install nodejs
