Comparison with 0 and JSLint error

[Rain Lover]

Here's the code:

<input type="number" value="0" id="input">
<script>
  if (document.getElementById('input').value == 0) {
    alert('Hello, world!');
  }
</script>

DEMO

And here's the JSLint error:

Expected '===' and instead saw '=='.

But when I listen to the advice and change == to ===, the alert stops appearing.

Hi there Rain Lover,

JSLint requires...

if (document.getElementById('input').value === '0')
