This mailing list is not used any more, Gitter is the place to ask questions Regards John On 02/10/2018, 20:17, "Marcel Ruff" <r...@netwake.com> wrote: Hi, when I use "let" or "const" from ES6 ES2015 ecmascript in qooxdoo I get: <class 'ecmascript.frontend.SyntaxException.SyntaxException'> : Unknown operator u'let' (pos (223, 7)) Does anybody know a simple way to at least use "let" and "const" in my code with the existing qooxdoo python framework? I have read https://github.com/qooxdoo/qooxdoo/issues/9285 and installed https://github.com/qooxdoo/qooxdoo-compiler but couldn't succeed to compile my existing application with "qx compile". Is JS based qx-compiler usable for legacy projects already?
