...g with "max" */
});
In both cases you have to iterate over the list and extract the value from each object.
Wouldn't it be better to somehow extract the values beforehand so that you don't have to do this in both callbacks individually? Yes! And that's what we can use .pipe() for:
deferred.pipe(f...

...ebase --strategy <s> learned the --strategy-option/-X option to pass extra options that are understood by the chosen merge strategy.
