I'd like to have my array items scrambled. Something like this:
[1,2,3,4].scramble => [2,1,3,4] [1,2,3,4].scramble => [3,1,2,4] [1,2,3,4].scramble => [4,2,3,1] and so on, randomly

How to Sort Hashes in Ruby. You are not limited to sorting arrays, you can also sort a hash. Example: hash = {coconut: 200, orange: 50, bacon: 100} hash.sort_by(&:last) # 50], [:bacon, 100], [:coconut, 200 This will sort by value, but notice something interesting here, what you get back is not a hash.
the shuffle command returns a randomized version of an array and if you want to randomize in place, you can just write @number.shuffle! Show activity on this post.
Well, the sort_by method expects a numerical value, that’s why length works. If you understand this, then you can use this method to do cool things, like sorting words that start with a capital letter & leaving everything else in place. def sort_by_capital_word (text) text .split .sort_by { |w| w [0].match?
