#33962 — object is undefined

var a={};
    a["b"]=123,
    a["c"]=456;
console.log(a["b"]);
undefined

var a={};
    a.b=123,
    a.c=456;
console.log(a.b);
undefined

Possibly because of the comma at the end of the line (instead of semi 
colon).

I posted without testing. In Chrome your code returns the correct value 
so it's probably something else you're doing.

The _return value of the method_ is _defined_ to be:

Doubtful.

The _return value of the method_, _definitely_.

Changing levels does that and it makes sense with

Default levels:
console.log("asdf")
VM168:1 asdf
undefined

Custom levels (like only Warnings and Errors):
console.log("asdf")
undefined

I considered the possibilities that the output may have appeared in another 
console, or not at all, and found them improbable.

No.
