Great! This will be really helpful:-D
How could I do the same with elements
of the same Array?
I'm not sure I follow, since the keys of an array will be unique so
there will be no opportunity to find matching keys within the same array.
If you just want matching values maybe you could write a loop that walks
through each element and turns that element into a hash with sha1Digest
to use as a key in the resulting array.
Two issues there, though:
1. I think using nulls in array keys may be verboten, so you'd probably
want to run the sha1 hash through base64Enode to use as a key.
2. You'll have to decide how to handle the original key names. They'll
be lost in this method, but if the point is to consolidate values
regardless of key maybe the key name doesn't matter.
