I'm trying to make my simple javascript function (no jQuery) log a message to the console when the browser is resized to over or under 890px. This code works on load, but only states the starting width when the page is loaded:

```
if (window.innerWidth < 890) {
     console.log('Less than 890px');
    } else {
     console.log('890px or more');
    }

```

But my code below using a window event doesn't work:

```
if (window.attachEvent) {
  window.attachEvent('onresize', function() {
    if (window.innerWidth < 890) {
     console.log('Less than 890px');
    } else {
     console.log('890px or more');
    }
})};

```

Can someone explain what I'm doing wrong here? I'm relatively new to javascript. Thanks for any help here.
