How do I convert a String object into a Hash object?
I have a string which looks like a hash: "{ :key_a => { :key_1a => 'value_1a', :key_2a => 'value_2a' }, :key_b => { :key_1b => 'value_1b' } }" How do I get a Hash out of it? like: { :key_a => { :key_1a => 'value_1a', :key_2a => 'value_2a' }, :key_b => { :key_1b => 'value_1b' } } The string can have any depth of nesting. It has all the properties how a valid Hash is typed in Ruby.
What does a double * (splat) operator do
Have you seen a function declared like this? def foo a, **b ... end I understand that a single * is the splat operator. What does ** mean?
