When we declare key and value in the hash, what's the difference between putting strings on key and key without strings?

Hi,

when we declare new hash and set keys and values. What's the difference if we set strings on keys and setting them without strings: example hash={"key" => "key", "value" => "value"} or without (" ") hash={key => "key", value => "value"}

Hey Filip, in Ruby, a hash can be created using either of the following: ``` hash = { key: value} or hash = { "key" => value} 

You can't use a bare word (a word without quotation marks) as a key. I has to be a "string" or a :symbol. I hope that helps.
