analogue for ActiveRecords' "where" for plain Ruby's arrays

Let's say i have an array of hashes with identical set of keys like:

array = [ 
  {attr1: val1, attr2: val2},
  {attr1: val3, attr2: val4} 
]

Thing is, i'd like to have some cool call like ActiveRecords' "where" to searh array above for specific elements. Something like

array.where(attr1: val1)

that will return all elements fitting the criteria. Using just plain Ruby.

Yes, there always is a good old .each but let's go full on pedal to the metal ruby-way here.

Thanks!

There is findand selectin ruby (for one or multiple results, respectively).

selected = array.select do |item|
  item[:attr1] == 'something'
end

select will pass each element of array to the block and pick those where the block returns a truthy value. find is similar but it will return the first element where the block returns a truthy value.
