Should JavaScript be split into two languages? New Google-driven proposal divides opinion • DEVCLASS

A Google engineer presented a proposal to the official standardization committee that would split JavaScript into two languages, a core to be implemented by runtime engines and a more capable variant which depends on tools that compile it down to that core. The presentation was at a meeting of Emca TC39 earlier this month, TC39 [https://tc39.es] being the committee of Ecma International that evolves the JavaScript (officially ECMAScript) specifiation. Shu-yu Guo, a staff software engineer at Google who specializes in JITs, VMs, compilers and standardization, made the presentation, with slides that were co-authored by Guo along with others from Mozilla, Apple, Moddable and Sony. Moddable is a company which offers an open source SDK for embedded programming, including the XS JavaScript engine.
