Using a placeholder variable to return undefined? Smart!
but in your code, if you do .html(0) it will return this.innerHTML
"but in your code, if you do .html(0) it will return this.innerHTML"
@williammalo, your previous code also reacted)
function(a,b){if(b=a!=undefined)this.innerHTML=a;return b?this:this.innerHTML}
Save 6 bytes?
function(a,b){return b!=a?(this.innerHTML=a,this):this.innerHTML}
@maettig
AH!
How did I not see that?
Good job :)
function(a,b){if(b!=a)this.innerHTML=a;return a?this:this.innerHTML}?
