I did not find any related subject in discussions or specs so here it is :
var f=function(name) {
this._name=name;
};
f.prototype={
get nodeName() {return this._name},
get tagName() {return this._name},
get anotherNameInvention() {return this._name},
...
set nodeName() {},
set tagName() {},
set anotherNameInvention() {},
...
};
So in that case we have to define several getters and setters for
something that is refering to the same object, slowing down the overall
script execution, it would probably be better to have something like :
f.prototype={
nodeName <operator> this._name,
tagName <operator> this._name,
anotherNameInvention <operator> this._name
...
}
var g=new f('test') --> g.nodeName is equal to g._name
While calling new the <operator> would indicate that g.nodeName must be
equal to g._name whether _name is a property or a method.
nodeName, tagName, etc could be defined in f but this does not solve the
case if we want them to be inherited properties.
Maybe no <operator> is required and the default behavior should be the
one described above (what could be the use of declaring something like
xxx : this.yyy in prototype ??? I have never seen it).
Example of use : js w3c dom implementation where objects own a lot of
redundant properties.
