Correct. This argument, IMO, is mainly made by programmers who are afraid of working in more than one language at once, traditionally .NET developers who are used to an entire, ready-made, tied-up-in-a-bow ecosystem being dropped on their doorstep. I have a lot of trouble sympathizing with that perspective (even though I've had multiple jobs as a full-time .NET developer).

JavaScript is not good. We should be working to get it out of the way, not converting everything in our environments to run on it.
