Javascript Get the Body Element

Getting the body of the document using javascript is very simple:

<script>   
    let body = document.body;
</script>

that will give you the Body element. You may also get it another way by running:

<script>

    let body = document.getElementsByTagName('body')[0];

</script>
```

However, if you use the second method you should either put the javascript at the end of the document or you'll need to load it inside of a `window.load` function like so:

```
<script>

    window.onload = function get_body() {
        let body = document.getElementsByTagName('body')[0];
    }

</script>

The easiest way is to call it directly from the document using document.body
