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();
    }
    ...
  };
};
