Is there an equivalent to `Array::sample` for hashes?

Question

I\'m looking to extract n random key-value pairs from a hash.

Answer 1

One way to accomplish this:

rank_hash = {"Listen" => 1, "Download" => 60, "Share" => 150, "Purchase" => 700 }

rank_array = rank_hash.to_a

Than call this to get random array sample of the k/v pair:

rank_array[rand(0..3)]

or this to not hard-code the arrays length:

rank_array[rand(0..(rank_array.length) -1)]

Example:

["Download", 60]
