This is not a track courses module so I've moved it to the Corner Bar.
The provided code,
<button onclick="sayHello('world')">Click Me</button>
after the code would mean before the
</body> tag. Just insert,
The first tag is known as the OPENTAG, where the attribute is written. The last tag is known as the ENDTAG, and never has any attributes.
id="result" is the attribute. It will be used as a `hook` in the script.
