How do I convert hash keys to method names?

Question

This is my hash:

tempData = {\"a\" => 100, \"here\" => 200, \"c\" => \"hello\"}

I need to access the hash keys as a method like:

Answer 1

If the hash is inside a module, you can define methods on that module (or class) dynamically using define_method. For example:

module Version
  module_function

  HASH = { 
    major: 1,
    minor: 2,
    patch: 3,
  }

  HASH.each do |name, value|
    define_method(name) do
      return value
    end
  end
end

This will define a Version module with major, minor, and patch methods that return 1, 2, and 3, respectively.
