Question

I think that my method is a little clumsy, and that there is likely to be a one-liner that I’m missing. Ideas?

def _to_hash 
    hsh = {}
    self.each_slice(2){|v| hsh[v[0]] = v[1]}
    hsh
end

1.9.3-p0 :003 > ["a", 1, "b", 2]._to_hash
{
    "a" => 1,
    "b" => 2
}

Answer 1

You want Hash’s .[] operator:

> Hash["a", 1, "b", 2]
 => {"a"=>1, "b"=>2}
