>not all ways of scoring a language are as good either

I feel you understand the author' point but still disagree for some reason.

I'll put the metaphor back to programming. There's programming for quality and programming for financial gain. If your metrics are the latter, then Javascript is the best language. But many people here do think as engineers, and thus there are other qualities that "are not as good" ways to score a language but maximize the ability to deliver a stable product.
