No because you still have to remember that rule whether you use semicolons everywhere or not.

Anyone who would write return\n deserves all they get.

It's a fun example, but it would never happen in real life.

    function getCount()
    {
        return 
        {
            'count': 1
        };
    }

Not what I'd do, but a common style nonetheless.

It's also completely valid JavaScript that does something very different than what it appears to.

    function getCount () {
      return undefined
      { // open code block
        'count': /*labelled line*/  1  //numeric expression
      } // close code block
    } // close function

LINE BREAKS CONSIDERED HARMFUL.

Which is why I'd say if you're writing javascript, use { brackets properly, and ; properly.

I agree, it's a common style, but a horrible one IMHO.
