Stream Piping and Error Handling

Spot the error-handling flaw when piping a readable stream into a writable stream.

Codejavascript

const fs = require('fs');
const zlib = require('zlib');

function compress(input, output) {
  const source = fs.createReadStream(input);
  const gzip = zlib.createGzip();
  const dest = fs.createWriteStream(output);

  source.pipe(gzip).pipe(dest);

  dest.on('error', (err) => {
    console.error('Compression failed:', err);
  });
}

compress('missing.txt', 'out.gz');
