Sorting: Sort array based on multiple conditions in Ruby

Question

I have a mulitdimensional array like so:

[
  [name, age, date, gender]
  [name, age, date, gender]
  [..]
]

I\'m wondering the best way to sort

Answer 1

You should always use sort_by for a keyed sort. Not only is it much more readable, it is also much more efficient. In addition, I would also prefer to use destructuring bind, again, for readability:

array.sort_by {|name, age| [age, name] }
