Question

So I know

variable && runTrue();

really means

if(variable){
    runTrue();
}

---

Then is there a more simplified way to write

if(variable){
    runTrue();
}else{
    runFalse();
}

instead of if-else?

Answer 1

Yes, I found out that this would do the same thing as a normal if-else:

(variable) && (runTrue(),1) || runFalse();

It is 2 characters shorter (still better than nothing) and tested in jsPerf that usually Short-circut evaluation - false for most of time is faster than the normal way of doing this.

(variable) &&           //If variable is true, then execute runTrue and return 1
(runTrue(),1) ||        // (so that it wouldn't execute runFalse)
runFalse();             //If variable is false, then runFalse will be executed.

But of course, you can always use variable?runTrue():runFalse();.
