Linting our code

Now, let's run eslint on our src/index.js to discover problems with our code:

$ npx eslint src/index.js

/home/dli/.d4nyll/.beja/final/code/6/src/index.js
  1:8 error Strings must use singlequote quotes
  2:1 error Expected 1 empty line after import statement not followed by another import import/newline-after-import
  3:24 warning Unexpected unnamed function func-names
  4:22 error A space is required after '{' object-curly-spacing
  4:51 error A space is required before '}' object-curly-spacing
  6:2 error Missing semicolon semi
  8:21 error Newline required at end of file but not found eol-last

 8 problems (7 errors, 1 warning)
  6 errors and 0 warnings potentially fixable with the `--fix` option.

Follow the instructions and fix those issues, or pass the --fix flag to have ESLint fix the issues for you automatically. At the end, you should end up with a file that looks like this:

import '@babel/polyfill';
import http from 'http';

function requestHandler(req, res) {
  res.writeHead(200, { 'Content-Type': 'text/plain' });
  res.end('Hello, World!');
}
const server = http.createServer(requestHandler);
server.listen(8080); // Note that there is a newline below this line
