  BRENDAN: ... But long story short, there was an idea in JavaScript that I was pursuing, and maybe a few others saw it, too, of a language that wasn’t C-like. It was easy to use. It was meant for people who were building things inductively. They were learning programming for the first time. And they didn’t necessarily have to know where semicolons had to go, or even curly braces. I lost the curly brace front. On the semicolon front I said, “It’s ridiculous to reject a program because of a missing semicolon. We should do some kind of error correction procedure.” So, I made one up on the spot and that became automatic semicolon push.

  [Laughter]

  CHUCK: I kind of hacked this in and it stayed.

  BRENDAN: Yup.

  AARON: That’s awesome.

  JOE: And 15 years later, people are still fighting over it.

  JAMISON: That’s every programmer’s nightmare, right?

  CHUCK: It’s so true.

  JAMISON: Just the hack [inaudible] that you made.

  AJ: I felt a sudden tremor in the force as if a thousand semicolons suddenly screwed up everything.

  [Laughter]

  BRENDAN: Yeah, there are definitely some issues there. But in fact, I remember Jamie Zawinski was writing some JavaScript and he had a long return expression so he put it on the next line with no semicolon after the return. And he was outraged that ASI would insert a semicolon after the return making the ‘return’ return the undefined value and the next line becomes dead code, a useless expression. It’s unreachable in the control flow of that function. He was totally outraged. [Laughs] But I said, “It’s too late. I can’t change it.” Once you ship things on the web, it’s very hard to change it.

  Végighallgattam ezt az interjút, érdekes volt. Brendan Eich egyébként egy zseni.

  Ezt még nem olvastam, de sejtettem, hogy valójában ilyen nevetséges a háttérsztori. Egyébként én támogatnám, hogy akár a régi fos kódok eltörésével erőltessük keresztül ennek az automatikus pontosvessző-beszúrásnak (szerepeljen már legalább egyszer magyarul is ) az eltörlését.
