[Solved] How to write a object to storage?

So I guess the issue is:

s.write('locale',`
exports.name = function() {return '${lang}'};
exports.temp = function(n){return n + '${locale[lang].tr}';};
exports.translate = function(t){return ${locale[lang].tr}[t];};
`);

You want something more like:

s.write('locale',`
exports.name = function() {return ${JSON.stringify(lang)}};
exports.temp = function(n){return n + ${JSON.stringify(locale[lang].t)};};
exports.translate = function(t){return ${JSON.stringify(locale[lang].tr}[t]);};
`);

Generally it's safer to use JSON.stringify than to try and quote it yourself :)
