Hi Folks,
Can someone tell me since which ECMA version the IN operator is available and which browsers (versions) support it ?
Explanation:
The IN-operator can be used like the following:
var myObject = {
Firstname: 'Foo',
Lastname: 'Bar'
};
if('Lastname' in myObject){
// Lastname is an attribute of myObject
}
