Hack: Get count of keys in a dict
Date: 2020-03-09 | hack | hacklang | dict |
I've been using a lot more hacklang at work and as such have run into a lot of use cases that don't seem to have too much documentation. One such use case is how to get the number of keys in a dict.
The hacklang standard library is actualy pretty uniform so similar to other Traversable's you might be trying to get the count of, you can get the count of keys in a dict with
$my_dict = dict[ 'a' => 1, 'b' =>2 ]; $my_count = C\count($my_dict);
