Re: How can I call variable in script like this global.var

I have tried your idea it's working but it's doesn't fully serve my main goal which is scoping 

that's what I did 
I ran this script over global 'var x = 5 ; var global = this; global.x' works perfectly, then I created another child object which has global as a prototype 


I ran this script over child object 'var x = 10 ; var child = this; child.x' 

but x=child.x=global.x  which totally make scence as child=global=this 

I want the global.x still the same without change any idea how can I do it.
