Javascript clean var and save memory?

[Porsche_maniak]

Hi guys.
Sometimes i have really big vars that take a lot of memory.
I am nulling them like this ?

var myvar='some big stack';
myvar=null;

The thing is that i am not sure if that works.
Some people say that myvar=false or myvar=undefined will do the trick.
Any thoughts?

Thanks

delete variable_name;

delete is possible only for global vars...
