I have a simple html page, which references a javascript module:
<head>
    <script type="module" src="mymodule.js"></script>
</head>
<body onload="doStuff()">
    . . . 
The javascript file looks like this:
export function doStuff() {
    console.log('test');
However, when I run this, I get the error:
columns.html:8 Uncaught TypeError: doStuff is not a function
    at onload (myPage.html:8)
If I change the HTML to:
<script src="mymodule.js"></script>
Then it works; however, this then doesn't let me reference a second javascript library from mymodule.js. My question is, why can it not find the function when it's referenced as a module?
