Hello, I’m also wondering when I see code examples in the RFC like:
$profit = [1, 4, 5]
|> loadMany(...)
|> fn(array $records) => array_map(makeWidget(...), $records)
|> fn(array $ws) => array_filter(isOnSale(...), $ws)
|> fn(array $ws) => array_map(sellWidget(...), $ws)
|> array_sum(...);
This would be way better on performances as a single foreach, no?
I feel like this pipe operator encourages coders to use array_* functions with
closures, which is often terrible performances compared to a loop.
How would the performance of the above compare with:
$profit = 0;
foreach (loadMany($input) as $item) {
$widget = makeWidget($item);
if (!isOnSale($widget)) {
continue;
}
$profit += sellWidget($widget);
}
