      var a = function() {};

      So that :
      - a validator which would check then var type wouldn't be surprised
      - the developer knows what a is supposed to be (even if it should be evident from a good naming convention and good comments)

      The way I read this, in the first example the function �b� is recreated (which would take time) every time �a� is called. Strictly speaking you would never call the same �b� function twice, but a new one each time. Or is that incorrect?



      For that reason alone I would never use the first example.

      With the difference that in the first way the function b is declared in the scope of function a

      Whereas in the second way function a and b are in the same scope

      (with indentation it would have clearer)

      A robust coding style demands that symbols should be declared before they are used. But how is this possible in the case of mutually recursive functions? If function a calls function b, and if function b calls function a, how can a and b both be declared before they are used?



      JavaScript provides two ways.



      var a = function () {



      var b = function () {



      ... a() ...



      };



      ... b() ...



      };



      var a;



      var b = function () {



      ... a() ...



      };



      a = function () {



      ... b() ...



      };
