Fun fact, I found, mostly by accident, that adding a comment to the beginning of a bookmarklet Chrome will set it to the name. I'd love to see the source code in Chrome that does this.

  javascript:/* name: /awesome# */alert(2+2)

Unable to reproduce this on Chrome 118. I just ended up with an untitled bookmark.

Still interesting to look at Chromium's source to see that they have unit tests for bookmarklets [1]. Also looks like people "frequently" report running JS from bookmarks as an XSS vulnerability [2]

Did you drag and drop it? Which OS? It works for me on Windows.

It doesn't seem to work on Chromium on Ubuntu. I don't have a Mac to try it on, perhaps someone else can try it.

Doesn't work on macOS for me. Huh.

What does "adding a comment to the beginning of a bookmarklet Chrome will set it to the name" mean, exactly?

This is a comment in JavaScript:

  /* comment */

Bookmarklets, like bookmarks, also have names.

I didn't phrase it very well but I figured people would just drag and drop it in Chrome and see it for themselves.

I'm not having trouble understanding the JS part ("a comment [at] the beginning of a bookmarklet"). It's the last part—understanding what it is that you're saying it's actually supposed to do ("will set it to the name") and what that would mean for bookmarklet usage that's giving me trouble.

I did. I spent way too long (15+ minutes) doing that, trying variations of the bookmarklet and user interactions to see if doing so would cause some observable difference and reveal some insight, and trying on different plausible (and implausible) interpretations of your comment.

Sorry about that. Which OS? It works for me on Windows.

When I drag and drop this to the Chrome bookmark bar, it will create a new bookmarklet with the name "awesome"

  javascript:/* name: /awesome# */alert(2+2)

Doesn't work on ChromeOS or Ubuntu.

Does it have to be two lines? Going to try this from home.

2 lines?

Edit: my bad, it was my mobile layout.

I mean does it need a line break as it is seen in your code?

I don't see a line break. Are you on mobile? Turn it sideways.
