Hi,
I saw for instance
Code JavaScript:
new google.translate.TranslateElement

but I could do only google.translate.TranslateElement

Code JavaScript:
var my = {name:'mytest'};
my.mytest = function() {
    alert(this.name);
}
 
my.mytest();
// I got mytest
var o = new my.mytest();
//I got undefined

What's the difference and what's the use of it ?
