See? The evolution of the language and its ecosystem was driven by the peculiar web needs. No surprise the language became what it is now. No surprise it sucks shit every time it spills out of its native domain.

As for C++ - there is a choice. With JS the choice is much more limited. You either rely on non-standard asm.js behaviour, lose DOM access with web assembly, or tolerate the stupidity and limitations of the language that far overgrown its tiny niche.

Btw., I am yet to hear how a language with a fixed syntax and no macros can be perceived as "highly expressive".
