I try to disallow user to change my javascript variables by using Developer tools like Firebug
My script so simple like..
var a = 1;
$('button').on('click',function(){
$('div').html(a);
});
My site allowed to change variables by Firebug, WHY ?
After I did a demo on Fiddle (http://jsfiddle.net/RjQTp/), That I just to know why Fiddle CANT change variables by Firebug.
Can someone expain me pls...
