on JavaScript at 18: Legal to Gamble
summary
JavaScript reaches 18 with concrete changes: ES6 adds arrow functions, default and rest parameters, ES6 modules and classes, symbols, maps and weakmaps, proxies and a formal iterable protocol. A verifiable subset plus WebGL typed arrays enables compiling C/C++ via ASM.js and Emscripten, running large engines like Unreal Engine 3 plug-in free, with demos showing near native performance (previously ~2x slower now about 1.33x on some benchmarks) and predictable memory behavior.
