new Object () can be defined from the object
, such as Object = new new Object var ();

but poor maintenance
Can function Hero (name) {// custom object class js not
this.name = name; // else have to add the phrase undefined
this.kill = function () {
doucument.write (this.name + "the kill Human ");
}
}
Var = new new Hero Hero ( "Yasuo");
hero.kill ();
good definition objects want to add a function of the prototype
var = new new Hero Hero ( "Yasuo");
Hero.prototype.ss = function () {// this object name Hero is not a type name
document.write ( "TOW the I Will the kill" this.name + + "S");
};
