Closures with functions as parameters

[limweizhong]

Hi,

Could anyone explain what happens when some function (x) is passed as a parameter into a function (b) which is nested inside a function(a), i.e.

a=function()
{
  b=function(t)
  {
    // what scope chain does t have in here?
  };
  b(x); // where x is some random function that could be externally defined.
};

hm, I don’t see anything special (functions are like any other variables) so I’d say the standard rules apply.

edit: btw, you code is not a closure.

Thanks for clarifying. I originally thought that running the parameter t as a function inside b would allow me to get to the variables inside a, or perhaps if t returns a function, that function would inherit the variables inside a. However, after some testing, I have found that it is incorrect.
