Default argument value helper
By Łukasz Jagodziński
An example showing how to write helper for setting default value of the argument using Tizen 2.3.
var def = function(v, d) {
return v === undefined ? d : v;
};
var test = function(a, b, c) {
a = def(a, true);
b = def(b, null);
c = def(c, '123');
console.log(a, b, c);
};
test();
test(false, 'x');
