Did you write this? If so, why did you add the "{}" at the end? Also, can't you use newlines in bookmarklets?

Yes, I wrote it.

The {} prevents the code from evaluating to a value that the browser then would use as the new value for the DOM, overwriting the existing page.

Try bookmarking javascript:123 and see what happens when you click it.

Bookmarklets are URLs, so a newline in the code would be urlencoded as %0A. So you could do:

javascript:alert(1)%0Aalert(2)

But I would prefer:

javascript:alert(1);alert(2)
