Video about RETRO'ed OcRam battle -plugins (still need some time to test everything before official release):
mysteryFunction(obj, js, arg_names, arg_values) {
let declarations = ''; let j = 0;
const arg_name_arr = (arg_names + ",").split(",");
arg_values.forEach(i => {
declarations += "let " + arg_name_arr[j] + " = arg_values[" + j++ + "];";
}); return function () { return eval(declarations + js); }.call(obj);
}
