I think it's also a question of using the tools that fit the problem. If the fashionable choice is to use C++ for example, a lot more can go wrong if the programmer isn't doing thing right. Now if you have the same situation with a higher level language, the worst that can happen is infinite loops. Most projects don't need the extra performance C++ would provide. So most of the time it's a better choice to use a higher level, more predictable language like Node.js or Go. Since ECMAScript engines like V8 have been optimised a lot in the last years too, the performance difference is not that high either.
