~95% of the JS code you see on the Web has semicolons. Apparently, a lot of programmers think it's worth that extra keystroke to avoid these types of bugs. I agree with them. The difficulty with programming isn't "Arrgh, there are too many keystrokes, my hands are tired!" It's "Arrgh, HTF did this bug get in here?!?"

They made it a named function, but this is literally how you format anonymous functions in js, a key feature that usually gets called with stuff like an onclick or onload call in the html domain.
