Page 7a
Simple Module Example
When this Web page loads, the following import script executes, from the header.
The script imports module file,
export-first-header.js.
Then the script calls module function,
function popupMessage(s), declared in export-first-header.js
.
The only parameter to popupMessage() is a string that says, First Module
,
however you can pass any string to popupMessage(), in your import file.
<script
type="module"
>
import * as m from './javascript/export-first-header.js';
// Use exported values from
// export-first-header.js:
m.popupMessage('First Module');
</script>
