Getting JavaScript to load when a webpage loads can be a consideration.
The following is by my understanding.
Lately I’ve been doing a lot of hands-on, physical tasks, as my posts have reflected. However, yesterday I had to incorporate some JavaScript into a web page. I’d done so many times in the past, but wondered if I’d done so the best way, if there’s a better way now, etc. I decided to look it up.
I discovered that a way to load JavaScript after the web page loads seems to be to put defer in the script tag where the JavaScript source is given: something like this:
<script src=”script.js” defer></script>
It seemed to work great.
