By Łukasz Jagodziński
An example showing how to create a function that can be executed only once using Tizen 2.3.
var once = function(f) {
var executed = false;
return function() {
if (!executed) {
executed = true;
f();
}
};
};
var test = once(function() {
console.log('x');
});
test(); // "x"
test();
test();
