| 19:26 | <sideshowbarker> | The existing statement “Function expressions in JavaScript are not hoisted” in MDN is correct, right? |
| 19:46 | <Ashley Claymore> | correct. |
| 19:48 | <nicolo-ribaudo> | Functions expressions do not need to be hosted because their binding is only visible inside their body, and no code can run before that binding initialization. |
| 19:48 | <nicolo-ribaudo> | I dislike @[Ashley Claymore]'s example, because swapping the two statements doesn't remove the error |
| 19:50 | <bakkot> | yeah it's more precise to say that 'hoisting' is not a thing which applies to expressions |
| 19:50 | <Ashley Claymore> | fair 🙂 I was going for a minimal way to write a function expression |
| 19:51 | <Ashley Claymore> | 💯 agree that showing that there is no external binding at all is the more important core |
| 19:53 | <nicolo-ribaudo> | looking at https://github.com/mdn/content/pull/11683 |
| 19:54 | <Ashley Claymore> | Yeah, maybe it’s not clear to them that only the RHS is considered the function expression. Maybe an ast-explorer link would help |
| 20:07 | <sideshowbarker> | nicolo-ribaudo: Ashley Claymore Thanks — I added a comment at https://github.com/mdn/content/pull/11683#issuecomment-1004327053 that goes into a bit more detail. |
| 20:08 | <sideshowbarker> | I cited https://stackoverflow.com/questions/3887408/javascript-function-declaration-and-evaluation-order/3887590#3887590 — which seems like a really good explanation in detail of what actually happens. |
| 20:12 | <sideshowbarker> | Thanks bakkot as well |
