Sorry its really not intended to be a personal attack and i regret the wording.

To clarify what I was trying to convey, the issue I personally find is that JS errors often produce difficult to understand descriptions and misleading traces when compared to some alternative languages.

I do believe that there is good work being done to convert these errors into more usable alternatives. Just recently I caught a glimpse of this: https://plus.google.com/+AddyOsmani/posts/DdWkiKsvbA2

Segmentation faults can also be very cryptic, especially in the memory related cases like you suggested, but its likely that any tool would behave in fairly unpredictable ways when it comes to any form of corruption or out of memory scenario.

Sorry again and hopefully that clarifies my thoughts.
