Re: Re: Why is 'else' demanded?

Maybe what I want to say is I don't want to write else statements, e.g.=0D
=0D
 mapHandler=0D
        .bind('shareInfo', function (ev, newVal) {=0D
            this.encapsulateShareInfo();=0D
            this.addLoadMap(newVal);=0D
            this.handleMarkers();=0D
            this.setInfoWindowAndCenter(newVal);=0D
        })=0D
...=0D
=0D
the code before refactor is:=0D
=0D
mapHandler=0D
        .bind('shareInfo', function (ev, newVal) {=0D
            if ($.isEmptyObject(newVal)) {=0D
                followDev.attr('isPollGps', true);=0D
                return;=0D
            }=0D
=0D
            if (this.ini) {=0D
                this.iniMapPage();=0D
                followDev.attr('isPollGps', true);=0D
                this.ini =3D false=0D
            }=0D
            if (this.curInfo =3D=3D this.shareInfo) {=0D
                return;=0D
            }=0D
            this.handleMarkers();=0D
            this.setInfoWindowAndCenter(newVal);=0D
        })=0D
=0D
the earlier code included several else statements and the complicated logic=

The else never gets executed or looked at in the case the if statement is=
=0D
true, so what exactly is the problem with it and what do you replace it=0D
with?=0D
