Right, so all we need to do is solve the halting problem... <smirk>

[kiwidrew → bigiain]

Yeah, so some syntactic rules (using Array.forEach() instead of for(;;) loops) and prohibiting some of Javascript's more dynamic features might be enough to render the language non-Turing complete. It would also -- and this is kind of the point -- render the language unable to perform certain computations that plain vanilla Javascript can perform.

The halting problem is about the general case, but when deciding a sane subset of JS, one can always be more conservative.

Yeah, if your subset of JavaScript is not Turing complete.
