The Alert command box

Once I make an alert command, the alert box doesn't pop up when I refresh the page. What can be the reason behind why It wont pop up?

Hi Michael.

There could be any number of reasons.

alert("Your message here");

Is how the syntax goes.

If you've included it in a function of your own make sure you've called it.

You can also check for console errors in your browser's DevTools. :)

File SCRIPT.JS must be nested in JS folder, otherwise SRC address is wrong.

I had a similar issue. Had the code exactly as written but wasn't popping up when ran. Try saving the updated script.js and index.html files then try running it. Mine ended up working after saving the files.
