B/c I don’t use the p5js online editor I don’t!

I can’t say for sure either.

What I do know is that most JS online hosts run our code inside an [`<iframe>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe), which by itself gets a little in the way when we need to debug it.

But by itself an [`<iframe>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe) shouldn’t interfere that much.

It would only make it harder to directly access global variables and that’s it.

My guess is that the p5js online editor goes further than that, w/ “features” like console logs redirection, “friendly” custom error messages and so on; which end up interfering w/ normal console debugging!

For most cases, where my sketches are small, I just use a simple text editor like Notepad2; and Atom for bigger 1s:

Once I’ve got them running properly I pick some JS host site:
