There is also this one   hash     foo   bar   baz   qux    hash map  amp  last     gt    bar    qux     Why it works   The  amp  calls to proc on the object  and passes it as a block to the method   something   i  i foo   something  amp  foo

It is as simple as   hash values    gt     a    b    c      b    c      this will return a new array populated with the values from hash  if you want to store that new array do  array of values   hash values    gt     a    b    c      b    c     array of values     gt     a    b    c      b    c

hash collect    k  v  v    returns    a    b    c      b    c       Enumerable collect takes a block  and returns an array of the results of running the block once on every element of the enumerable  So this code just ignores the keys and returns an array of all the values   The Enumerable module is pretty awesome  Knowing it well can save you lots of time and lots of code
