My alert boxes and boom message as well as the console message works just fine but the original hello javascript message doesn't appear initially.
When I comment out the alerts etc it shows up.
What am I missing? Why do the alert boxes appear to stop the original message from rendering?

Full Stack JavaScript Techdegree Student 6,425 PointsIf you have the old code from the previous lesson, your <script> tag might be placed in the <head> section. Therefore the initial JavaScript message in the <h1> tag is not allowed to display until after your script. To fix this, just set the <script> tag near the closing </body> tag. This way your <h1> is allowed to displayed before the script.js and should work as desired.
<!-- here's where you should put the script -->
<script src="js/script.js"></script>
</body>
</html>

If you see a different behavior in the video, it could be because page rendering used to be done differently in older browsers.

Full Stack JavaScript Techdegree Student 980 PointsI also see this behaviour... I was under the impression that positioning the script tag at the bottom of the body as the last item.... would ensure that this script is run after the "Hello, Javascript! header appeared on the webpage?
Is this not the case?
