I think he is talking about badly written JS code serving the APIs and the overhead of it.

Of course it's hard to debate whether JS, Java or PHP is most inefficient in that regard.

I strongly believe that the efficiency of an API is 1% down to the language it's coded in, and 99% down to who coded it.

[yjftsjthsd-h]

Yes and no; while it's still true that you can write FORTRAN in any language, there are network effects that mean the effort required to write efficient code is different per language/community/framework.

I think that’s true if you take a no dependencies approach but as soon as you tap into the ecosystem the argument is lost.

[onion2k]

Not really. It still depends on who coded it. It's just that there's more people involved now.

Corollary: The average API is far less efficient than the languages you like to complain about their efficiency.
