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

what about using bind

function funcA(param) {     
    var bscoped = funcB.bind(this);     
    bscoped(param1,param2...)
}
