How do I get "my_param" as a string so that I can use it as a key in the has I am trying to create?

var my_function = function(my_param) {
  var my_hash = { 
    my_param: "foobar"
  }
}

Answer 1

var my_hash = {};
my_hash[my_param] = 'foobar';

This is bracket notation, where a.b = 'c' is the same as a['b'] = 'c'.

Answer 2

You'll want to use bracket notation:

var my_hash = {};
my_hash[my_param] = "foobar";
