Try the following variation of JJ's code:
function Counter() {
var theValue = 0;
return {
getVal: function() {
return theValue;
},
increase: function() {
return ++theValue;
},
decrease: function() {
return --theValue;
}
};
}
It can be used in the following way:
var c1 = Counter(), c2 = Counter();
c1.getVal() ===> 0
c1.increase() ===> 1
c1.getVal() ===> 1
c2.getVal() ===> 0
