Yes, it is possible, but remember to NOT put the var keyword in front of it inside the function.

ERORR - DOES NOT WORK:

var variable = before;



change();



alert(variable);



function change() {



  var variable = after;



}

WORKS:

var variable = before;



change();



alert(variable);



function change() {



  variable = after;



}
