I am new to requirejs and don't understand variable scope.
So previously, for example, I had:
var Foo = "some value";
function firstFunction () {
    //do something with Foo here
    console.log(Foo); 
    }
 function secondFunction () {
    //do something else with Foo here
    console.log(Foo); 
    }
But within a module
define(function() {
   return {
      //how do I declare Foo within the module so it is available to firstFunction and secondFunction?
      firstFunction: function() {
          //do something with Foo here
          console.log(Foo);
          },
      secondFunction: secondFunction () {
         //do something else with Foo here
         console.log(Foo);
         }
     }
    });
Is there a way of declaring the variable Foo within the module and to make it available to firstFunction() and secondFunction()?
