You can't as those are local functions within different scopes and are not accessible from each other. If you need to call e() from inside f()'s scope, then e() shouldn't be defined within c()'s scope, but within b(), where it will be visible in f()'s scope.

You can't. That's the whole point of scoping.

You can, however, make the variable e available to the parent scope by declaring it outside the function c.

a = function b() {
  var c, d, e;
  c = function () {
    e = function () {
      ...
    };
    ...
  };
  d = function () {
    function f() {
      e();
    }
    ...
  };
};
