Question: How do I pop up an alert in JavaScript?

I tried `alert"HELLO"` but that didn't work.

Can someone tell me the correct syntax?

Answer: 
Unlike VBScript, JavaScript requires parentheses around function calls.

Therefore, you need to write `alert("Hello!");`

It's also preferable (but not required) to end every statement with a semicolon `;`.

Finally, if you aren't already, you need to put it in a script block, like this:

```
<script type="text/javascript">
    alert("Hello!");
</script>

```

You can put JavaScript inside a script tag in an HTML page, or you can make a standalone `.js` file and double-click on it (in Windows) to run it using WSH.
Just add parentheses and enclosed it within the script tag.

```
<script type="text/javascript" >
  alert("hello");
</script>

```
