####### to do
|
|
- make a button to destroy something and see what functions run (detach/destroy?)
|
|
- use "The Dirty Flush pattern" somewhere
|
|
"You don't remember that chapter? That's because I just invented that name. Gross. ""
|
|
- "Side Effect City" - Even the callbacks have side effects...
|
|
- maybe propose some changes to the dev mode output to make things more readable
|
|
- Can `dirty` ever contain anything besides a single integer? In other words, are elements updated one after the next, or can `update` sometimes operate on more than one element at a run?
|
|
- no, because `make_dirty` only does its thing if dirty is [-1]:
|
|
- but try with a click handler that updates two props and see what happens to `dirty`
|
|
```js
|
|
function make_dirty(component, i) {
|
|
if (component.$$.dirty[0] === -1) {
|
|
dirty_components.push(component);
|
|
schedule_update();
|
|
component.$$.dirty.fill(0);
|
|
}
|
|
component.$$.dirty[(i / 31) | 0] |= (1 << (i % 31));
|
|
}
|
|
|
|
```
