Hi Salar, thank you so much for sharing your knowledge with us <3

Hi Salar, at first for const num2 I had typed parstFloat instead of parseFloat so I got my alert to work. -ha! Then I ran the program and my JS warning says, “Failed to execute ‘write’ on ‘Document’: It isn’t possible to write into a document from an asynchronously-loaded external script unless it is explicitly opened.”
Not sure what that means… thanks for your tutorial… 💗… Cheers!
Edit: so I think I figured it out. At first, I put my JS link at the head tag with ‘defer’ but the console didn’t like that. So I moved my script tag to the bottom of my index page just before the closing body tag, now I can see my calculator working in the open browser window. But the console is still complaining: it says
“[Violation] Avoid using document.write( ).” I’m checking it out a bit later today, I’ll let you know what I find out, thanks!

hi sir, thank you for this work
But I have an observation, Why is the code not working when I link from an external script, but then works when I enter the a script at the bottom of the hmtl page?

How can you loop this without to refresh the page all the time?
