JavaScript pass scope to another function

Question

Is it possible to somehow pass the scope of a function to another?

For example,

function a(){
   var x = 5;
   var obj = {..};
   b()         


        

Answer 1

function a(){
   var x = 5;
   var obj = {..};
   var b = function()
   {
        document.println(x);
   }
   b.call();
}
