In this paper we present the incompatibility and complexity problems in Web development when using JavaScript. We also demonstrate the solution given by transcompilers and/or languages that compile to JavaScript, but we also highlight the respective problems.

Thus, we present our proposal, i.e, a meta-transcompiler, that targets to harmonize JavaScript-oriented web development and tight the feedback loop between web standards’ editors and web developers, even during the transition period of work-in-progress specifications, such as the upcoming ECMAScript 6 “Harmony” specification.
