V8 won't always be required for fast Javascript. If Web Assembly[1] pans out as planned, I can foresee embedded devices that can execute wasm code natively (or at least fast)
Web assembly, as well as asm.js, is never meant to be manually written. It's a target for compilers. And even the most efficient ever implementation of web assembly won't make your plain old javascript any faster.
Kinda stupid reason.
> more high-level that are not thereby made somewhat more difficult
Usually, the higher the level of the language, the easier it is to use. I would never call JS an easy language.
