odd JS behavior

x = {"a":3};
if (x.a) 4; else 5;

run in node.js:

> x = {"a":3};
{ a: 3 }
> if (x.a) 4; else 5;
4
>

run in espruino:

>x = {"a":3};
={ "a": 3 }
>if (x.a) 4; else 5;
=undefined
>

similarly if (x.b) 4; else 5; returns 5 in node.js and undefined in Espruino.

I'm not sure what ECMA defines as 'return' from a statement. That's why some languages by definition return self / this except there is a coded return... a default return allows easy and especially with Espruino very fast cascading of messages sent / methods invoked to the very same object...

Interesting... I honestly wasn't aware that if statements returned anything - so it doesn't surprise me that it's wrong. It should be a pretty easy fix though. I just added a bug for this: espruino/Espruino#909
