Given that LLJS is nearly C, would be great to have C as a potential compile target (using stdlib & malloc instead of ArrayBuffer). Or even Objective C.
Having one language to target the web as well as native would just be plain awesome. Plus, adding language features such as Classes, forEach loops etc (ES6?) would be a lot easier with LLJS. There's no reason it needs to be as plain as C.
LLJS is a superset of JS, so compiling it to C would be very difficult. You need a VM as well, GC, etc ..
Imagine the examples on your homepage being converted to C and compiled to native, very do-able right?
