Why does this c

Answer 1

You can reffering to foo by this statement.

You should write a wrapper like below which will very helpfull if will we wanted to change the name of the foo when we will have a lot of function in foo

var foo = {
    bar: function() { return this.baz; },
    baz: 1
  };

(function(a){
 for( var i in a){ 
    if( typeof a[i] === "function" ){

      a[i] = (function(f){  
            return function(){
                return f.apply(a,arguments);
            }
      })(a[i])
    }
 }
})(foo);

  (function(){
    return typeof arguments[0]();
  })(foo.bar);
