I have an array of hashes as follows:
array = [{"name"=>"Nish", "age"=>27, "place"=>"xyz"},
{"name"=>"Hari", "age"=>26, "place"=>"xyz"},
{"name"=>"Anan", "age"=>28, "place"=>"xyz"}]
I want to select the hashes with age 27 and 26
How to achieve that.
This will do it:
array.select { |user| [26, 27].include?(user['age']) }
The 'select' will choose any elements that match the provided block.
You can make use of between?
array.select{ |a| a['age'].between?(26, 27) }
This will return you only the hash which has age between 26 and 27
Or You can use include? to check for specific age
array.select{ |a| [26, 27].include? a['age'] }
between? in this situation. There is nothing in OP's question that would suggest that it's appropriate.include?, I think one of, when I see between? I think within the bounds of. Both are equally easy to read, only one is what OP wanted. What if 26 and 27 were just an example?
between? even more readable than include? in this case : read as an english sentence, the first example is easier to parse IMHO.
